Vacation days The distribution of the number of vacation days per year offered by different U.S. companies is skewed to the right.

a. We collect data on the number of vacation days from a random sample of 60 companies across the United States. Why is it okay to use these data for inference even though the population is skewed?
b. The mean and standard deviation of the 60 companies in our sample were 22 days and 9 days, respectively. Specify the sampling model (shape, center, spread) for the mean number of vacation days of such samples.
c. Find a 95% confidence interval for the mean number of vacation days offered by U.S. companies.
d. Explain what "95% confidence" means in this context.
