MATH221 Statistics for Decision Making Week 6 Lab Name:_______________________ Statistical Concepts: Confidence IntervalsData SimulationNormal Probabilities Short Answer Writing Assignment All answers should be complete sentences. In the Week 2 Lab, you found the mean and the standard deviation for the SLEEP variable for both males and females.Use those values for follow these directions to calculate the numbers again. (From Week 2 Lab: Calculate descriptive statistics for the variable Sleep by Gender.Sort the data by gender by clicking on Data and then Sort.Copy the Sleep of the males from the data file into the Descriptive Statistics worksheet of the Week 1 Excel file.[Write down the mean and standard deviation.] These are sample data. Then, copy and paste the female data into the Descriptive Statistics workbook and do the same.Keep three decimal places.) You will also need the number of males and the number of females in the dataset.You can actually count these in the dataset. Then use the Week 5 spreadsheet to calculate the following confidence intervals.The male confidence interval would be one calculation in the spreadsheet and the females would be a second calculation. Give and interpret the 95% confidence intervals for males and a second 95% confidence interval for females on the SLEEP variable.Which is wider and why? Give and interpret the 99% confidence intervals for males and a second 99% confidence interval for females on the SLEEP variable.Which is wider and why?Give and interpret the 95% confidence interval for the size of students’ shoes. Give and interpret the 99% confidence interval for the size of students’ shoes.Compare the 95% and 99% confidence intervals for the size of students’ shoes. Explain the difference between these intervals and why this difference occurs. Find the mean and standard deviation of the DRIVE variable by copying that variable into the Week 1 spreadsheet. Use the Week 4 spreadsheet to determine the percentage of data points from that data set that we would expect to be less than 25.To find the actual percentage in the dataset, sort the DRIVE variable and count how many of the data points are less than 25 out of the total 35 data points.That is the actual percentage.How does this compare with your prediction?What percentage of data would you predict would be between 25 and 50 and what percentage would you predict would be more than 50 miles?Use the Week 4 spreadsheet again to find the percentage of the data set we expect to have values between 25 and 50 as well as for more than 50.Now determine the percentage of data points in the dataset that fall within each of these ranges, using same strategy as above for counting data points in the data set.How do each of these compare with your prediction and why is there a difference? We need to find the confidence interval for the SHOE SIZE variable.To do this, we need to find the mean and standard deviation with the Week 1 spreadsheet.Then we can the Week 5 spreadsheet to find the confidence interval.This does not need to be separated by males and females, rather one interval for the entire data set. First, find the mean and standard deviation by copying the SHOE SIZE variable and pasting it into the Week 1 spreadsheet.Write down the mean and the sample standard deviation as well as the count. Open the Week 5 spreadsheet and type in the values needed in the green cells at the top to find the confidence interval. Change the confidence level to 99% to find the 99% confidence interval for the SHOE SIZE variable.

If showing the answer in %, have two decimal places.Answer the following problems showing your work and explaining or analyzing your results.

Once a month, a business card is pulled out to award one lucky diner with a free meal. Identify which type of sampling is used and why. (2 pts)A test of the effectiveness of a new curriculum could begin by dividing an area by school district, then choosing a school or set number of schools at random and sampling students from each. Identify which type of sampling is used and why. (2.5 pts)A survey about timekeeping might divide the population by time zone, then take 100 random samples per zone. Identify which type of sampling is used and why. (2.5 pts)A local TV station conducts an “Instant Poll” to predict the winner in the upcoming mayoral election. Evening news viewers were invited to phone in their votes, with the results to be announced on the late-night news. Based on the phone calls, the station predicted that Joseph Serra would win the election with 52% of the vote. They were wrong: Serra lost, getting only 46% of the vote. This faulty prediction may be the consequence of what kind of bias? (2.5 pts)According to Abyss Consulting, the average age of viewers of “America’s Got Talent” is 25 years old. However, the producer of the show thinks it is higher than 25.

Scenario Analysis, statistics homework help
Scenario:The owner of a small printing
company is considering the purchase of additional printing equipment to expand
her business. If the owner expands the business and sales are high, projected
profits (minus the cost of the equipment) should be $90,000; if sales are low,
projected profits should be $40,000. If the equipment is not purchased,
projected profits should be $70,000 if sales are high and $50,000 if sales are
low.
Are there options other than the purchase of additional
equipment that should be considered in making the decision to expand the
business?
If the owner is optimistic about the company’s future
sales, should the company expand by purchasing the equipment?
Is the owner’s optimism or pessimism about sales the
only factor that may impact the company’s profits?
The equipment to be purchased is known in the industry
to have a useful life of five years. How might this impact the printing
company?
