A nurse manager has job offers from 3 different hospitals. To explore the offers further, she asked a sample of nurse managers how many months each worked for the unit/hospital before receiving a raise in salary.

The sample information is:

Number of Months before First Raise in Salary

Hospital A	Hospital B	Hospital C
12	12	11
10	11	12
14	8	13
12	9	8

At the 0.05 level of significance, is there a difference in the mean numbers of months before a raise was granted among the three units/hospitals?

a. Set up the null and alternative hypotheses.

b. Formulate the Decision Rule. Use 0.01 level of significance.

c. What's your decision regarding the null hypothesis? Why? What can we conclude?

d. Make sure to provide the ANOVA table and all the computations involved for computing the value of F-statistic.
