Southern New Hampshire University Statistics Discussion
Option 2:
A professor states that in the United States the proportion of college students who own iPhones is .66. She then splits the class into two groups: Group 1 with students whose last name begins with A-K and Group 2 with students whose last name begins with L-Z. She then asks each group to count how many in that group own iPhones and to calculate the group proportion of iPhone ownership. For Group 1 the proportion is p1 and for Group 2 the proportion is p2. To calculate the proportion you take the number of iPhone owners and divide by the total number of students in the group. You will get a number between 0 and 1.
What would you expect p1 and p2 to be?
Do you expect either of these proportions to be vastly different from the population proportion of .66?
Would you be surprised if p1 was different than p2?
Would you be surprised if they were the same or similar?
What statistical concept describes the relationship between the first letter of someone's last name and whether or not they own an iPhone?
STUDENT 1: Respond to this students discussion post in response to Option 2 (above)
I would expect that the percentage of iPhone users in both P1 and P2 to be similar. I think this might also depend on weather or not the college students are from the same area, or the same college. Overall, I'd expect them to be about the same even though P2 has more people in the sample. I would expect the proportion to be a little bit higher than the population proportion. I say this because I think college students tend to invest in technology a little bit more than the average person. They use computers and phones constantly, so they may be more inclined to go for the Apple products due to popularity. I would be pretty surprised if P1 was vastly different than P2. I wouldn't see why a random sample like this would yield two different results. This sample seems very random, so I would think it would yield similar results. I would not be surprised if they were similar at all. The concept in this problem is Probability, in this case .66 or 66%.

QSO 510 Southern New Hampshire University Computer Chips Scenario Analysis HW
A manufacturer of computer chips has a computer hardware company as its largest customer. The computer hardware company requires all of its chips to meet specifications of 1.2 cm. The vice-president of manufacturing, concerned about a possible loss of sales, assigns his production manager the task of ensuring that chips are produced to meet the specification of 1.2 cm.Based on the production run from last month, a 95% confidence interval was computed for the mean length of a computer chip resulting in: 95% confidence interval: (0.9 cm, 1.1 cm)
What are the elements that the production manager should consider in determining his company's ability to produce chips that meet specifications?
Do the chips produced meet the desired specifications?
What reasons should the production manager provide to the vice-president to justify that the production team is meeting specifications?
How will this decision impact the chip manufacturer's sales and net profit?

SYM 506 GCU Discrete Probability Distributions and Data Analysis Exam Practice
Q 1.An auditor for Health Maintenance Services of Georgia reports 40% of policyholders 55 years or older submit a claim during the year. Fifteen policyholders are randomly selected for company records.a. How many of the policyholders would you expect to have filed a claim within the last year?b. What is the probability that 10 of the selected policyholders submitted a claim last year?c. What is the probability that 10 or more of the selected policyholders submitted a claim last year?d. What is the probability that more than 10 of the selected policyholders submitted a claim last year?Q 2. (Data Analysis)Refer to the Baseball 2016 data. Compute the mean number of home runs per game. To do this, first find the mean number of home runs per team for 2016. Next, divide this value by 162 (a season comprises 162 games). Then multiply by 2 because there are two teams in each game. Use the Poisson distribution to estimate the number of home runs that will be hit in a game. Find the probability that:a. There are no home runs in a game.b. There are two home runs in a game.c. There are at least four home runs in a game.Q 3.Management at Gordon Electronics is considering adopting a bonus system to increase production. One suggestion is to pay a bonus on the highest 5% of production based on past experience. Past records indicate weekly production follows the normal distribution. The mean of this distribution is 4,000 units per week and the standard deviation is 60 units per week. If the bonus is paid on the upper 5% of production, the bonus will be paid on how many units or more?Q 4.Best Electronics Inc. offers a “no hassle” returns policy. The daily number of customers returning items follows the normal distribution. The mean number of customers returning items is 10.3 per day and the standard deviation is 2.25 per day.a. For any day, what is the probability that eight or fewer customers returned items?b. For any day, what is the probability that the number of customers returning items is between 12 and 14?c. Is there any chance of a day with no customer returns?Q 5Refer to the Lincolnville School District bus data.a. Refer to the maintenance cost variable. The mean maintenance cost for last year is $4,552 with a standard deviation of $2332. Estimate the number of buses with a maintenance cost of more than $6,000. Compare that with the actual number. Create a frequency distribution of maintenance cost. Is the distribution normally distributed?b. Refer to the variable on the number of miles driven since the last maintenance. The mean is 11,121 and the standard deviation is 617 miles. Estimate the number of buses traveling more than 11,500 miles since the last maintenance. Compare that number with the actual value. Create a frequency distribution of miles since maintenance cost. Is the distribution normally distributed?Q 6Refer to the Century National Bank data. Is it reasonable that the distribution of checking account balances approximates a normal probability distribution? Determine the mean and the standard deviation for the sample of 60 customers. Compare the actual distribution with the theoretical distribution. Cite some specific examples and comment on your findings.Divide the account balances into three groups, of about 20 each, with the smallest third of the balances in the first group, the middle third in the second group, and those with the largest balances in the third group. Next, develop a table that shows the number in each of the categories of the account balances by branch. Does it ap-pear that account balances are related to the branch? Cite some examples and comment on your findings.***Note: Files containing the following Data is attached below Baseball 2016 dataLincolnville School District bus data.Case A, Century National Bank is attached

SWC Stats Alcoholic Beverages a Student Consumes Question
Use this activity to assess whether you and your peers can: Use StatCrunch to conduct a hypothesis test to test a claim about a population mean.State an appropriate conclusion in context.Explain the meaning of each relevant item from the StatCrunch output.ContextA group of 75 college students from a liberal arts college were randomly sampled and asked about the number of alcoholic drinks they have in a typical week. The file containing the data is linked below. The purpose of this study (Links to an external site.) was to compare the drinking habits of the students at the college to the drinking habits of college students in general. In particular, the dean of students, who initiated this study, would like to check whether the mean number of alcoholic drinks that students at his college have in a typical week differs from the mean of U.S. college students in general, which is estimated to be 4.73.VariablesThe number of alcoholic beverages a student consumes in a week.DataOpen the drinks datafile in the Stats at Cuyamaca College group on StatCrunch (directions - opens in a new tab).Note - the drinks datafile is different from the college_drinking file.PromptThe drinks datafile is available in the Data section above.Let 𝜇μ be the mean number of alcoholic beverages that students in the liberal arts college drink in a typical week.
