The average number of vacation days per year offered by different US companies is skewed to the right. A random sample of 60 companies showed the mean number of vacation days was 22, and the standard deviation was 9 days.

1- Why is it OK to use these data for inference even though the population is skewed?

2- Find a 95% confidence interval for the mean number of vacation days offered by US companies.
