Question: Executives at the Walt Disney Company are interested in estimating the mean spending per capita for people who visit Disney World in Orlando, Florida. Since they do not know the population standard deviation, they plan to use the t-distribution to conduct the test. However, they realize that the t-distribution requires that the population be normally distributed. Six hundred customers were randomly surveyed, and the amount spent during their stay at Disney World was recorded. These data are in the file called Disney. Before using these sample data to estimate the population mean, the managers wish to test to determine whether the population is normally distributed.
a. State the appropriate null and alternative hypotheses.
b. Organize the data into six classes and form the grouped data frequency distribution.
c. Using the sample mean and sample standard deviation, calculate the expected frequencies, assuming that the null hypothesis is true.
d. Conduct the test statistic and compare it to the appropriate critical value for a significance level equal to 0.05. What conclusion should be reached? Discuss.
