Answer 1

ANSWER::

The hypothesis being tested is:

H0: µ1 = µ2 = µ3

Ha: Not all means are not equal

The SPSS output is:

The p-value is 0.000.

Since the p-value (0.000) is less than the significance level (0.05), we can reject the null hypothesis.

Therefore, we can conclude that the amount of stress differs for three groups of employees.
