In a random sample of five people, the mean driving distance to work was 24.3 miles and the standard deviation was 4.5 miles. Assume the population is normally distributed and use the t-distribution to find themargin of error and construct a 95% confidence interval for the population mean µ. Interpret the results.Identify the margin of error.(Round to one decimal place as needed.)Construct a 95% confidence interval for the population mean.10(Round to one decimal place as needed.)Interpret the results. Select the correct choice below and fill in the answer box to complete your choice.(Type an integer or a decimal. Do not round.)A. It can be said that % of the population has a driving distance to work (in miles) that is between the interval's endpoints.B. With% confidence, it can be said that most driving distances to work (in miles) in the population are between the interval's endpoints.% confidence, it can be said that the population mean driving distance to work (in miles) is between the interval's endpoints.% of all random samples of five people from the population will have a mean driving distance to work (in miles) that is between the interval's endpoints.C. WithD.

Use the given data values (a sample of female arm circumferences in centimeters) to identify the corresponding z scores that are used for a normal quantile plot, then identify the coordinates of each point in the normal quantile plot. Construct the normal quantile plot, then determine whether the data appear to be from a population with a normal distribution. a. List the z scores for the normal quantile plot. (Round to two decimal places as needed. Use ascending order.) b. identify the coordinates of each point in the normal quantile plot. Use ordered pairs for the form (x,y), where x is the sorted arm circumferences in ascending order, and y is the corresponding z score. (Round to two decimal places as needed. Use ascending order.)

Suppose you are a market analyst for a company that produces headphones, and want to determine if customers value different prototype designs differently on average. You are provided 5 different prototype models of the latest headset, and are able to sample 21 people per prototype and ask them to provide their rating based on a particular scale. Research yields a SSTotal of 109746, along with a sum of square error (SSE) of 89761. Using this information, conduct a one-way ANOVA test to determine if there is any difference between the average values consumers place on the different headphone designs, using a significance level of 10%. What is the correct interpretation of your analysis?
