Question
A union of restaurant and foodservice workers would like to estimate this year's mean hourly wage, u, of foodservice workers in the U.S. Last year's mean
hourly wage was $8.08, and there is reason to believe that this year's value is different from last year's.
The union decides to do a statistical test to see if the value has indeed changed. The union chooses a random sample of this year's wages, computes the mean
of the sample to be $8.48, and computes the standard deviation of the sample to be $1.25.
Based on this information, answer the questions below.
