9.50 Paid days off and the single-sample t test: The
number of paid days off (e.g., vacation, sick leave) taken
by eight employees at a small local business is compared
to the national average.You are hired as a consultant by
the new business owner to help her determine how
many paid days off she should provide. In general, she
wants to set some standard for her employees and for
herself. Let's assume your search on the Internet for
data on paid days off leaves you with the impression
that the national average is 15 days. The data for the
eight local employees during the last fiscal year are: 10,
11, 8, 14, 13, 12, 12, and 27 days.
