2.How many variables are in this data set?
3.How many observations are in this data set?
4.Name the variables and indicate whether they are categorical or quantitative.
Question 2
A student has completed 20 courses in the School of Arts and Sciences. Her grades in the 20 courses are shown below.
1.Develop a frequency distribution and a bar chart for her grades.
2.Develop a relative frequency distribution for her grades and construct a pie chart.
Question 3
The number of hours worked per week for a sample of ten students is shown below.
1.Determine the median and explain its meaning.
2.Compute the 70th percentile and explain its meaning.
3.What is the mode of the above data? What does it signify?
Question 4
You are given the following information on Events A, B, C, and D.
1.Compute P(D).
2.Compute P(A ∩ B).
3.Compute P(A | C).
4.Compute the probability of the complement of C.
5.Are A and B mutually exclusive? Explain your answer.
6.Are A and B independent? Explain your answer.
7.Are A and C mutually exclusive? Explain your answer.
8.Are A and C independent? Explain your answer.
Question 5
1.When a particular machine is functioning properly, 80% of the items produced are non-defective.
2.If three items are examined, what is the probability that one is defective?
3.Use the binomial probability function to answer this question.
Question 6
The average starting salary of this year’s graduates of a large university (LU) is $20,000 with a standard deviation of $8,000. Furthermore, it is known that the starting salaries are normally distributed.
1.What is the probability that a randomly selected LU graduate will have a starting salary of at least $30,400?
2.Individuals with starting salaries of less than $15,600 receive a low income tax break. What percentage of the graduates will receive the tax break?
3.What are the minimum and the maximum starting salaries of the middle 95.4% of the LU graduates?
Question 7
A simple random sample of 6 computer programmers in Houston, Texas revealed the sex of the programmers and the following information about their weekly incomes.
1.What is the point estimate for the average weekly income of all the computer programmers in Houston?
2.What is the point estimate for the standard deviation of the population?
3.Determine a point estimate for the proportion of all programmers in Houston who are female.
Question 8
Students of a large university spend an average of $5 a day on lunch. The standard deviation of the expenditure is $3. A simple random sample of 36 students is taken.
1.What are the expected value, standard deviation, and shape of the sampling distribution of the sample mean?
2.What is the probability that the sample mean will be at least $4?

Ashford University Statistics Normal Distribution and Sizing Question
Respond to one of the following options in your initial post, citing at least one specific credible source in support. Question on credible sources? See the Scholarly, Peer-Reviewed, and Other Credible Sources (Links to an external site.).
Option 1
Determine whether there is any link between the normal distribution and Variation 2: Standard Deviation (With a Digression on Eggroulette) (Links to an external site.) where we relied on statements such as “about two-thirds of observations are within one standard deviation of the mean.”
Briefly discuss.
Option 2
State an example of a variable that follows a normal distribution.
State one way knowing this is useful in your professional or personal life.
Briefly elaborate on your example.
Option 3
Identify the minimum number of data points needed to generate a normal distribution.
Create a data set of that size, and show that it meets the first three conditions for a Normal Distribution in section 5.1 on page 164 of the text.
