The XYZ Corporation is interested in possible differences in days worked by sala

Question

The XYZ Corporation is interested in possible differences in days worked by salaried employees in three departments in the financial area. A survey of 23 randomly chosen employees reveals the data shown below. Because of the casual sampling methodology in this survey, the sample sizes are unequal. Research question: Are the mean annual attendance rates the same for employees in these three departments?

Based on the given hypotheses, choose the correct option
    H0: 1 = 2 = 3
    H1: Not all the means are equal
    = 0.05

On the basis of the above findings, we cannot reject the null hypothesis.

    

Based on the given hypotheses, choose the correct option.
     H0: 21 = 22 = 23
     H1: Not all the variances are equal
      = 0.05

On the basis of the above-determined Hcalc, we fail to reject the null hypothesis.

Explanation / Answer

following information has been generated using ms-excel

(third part) Reject the null hypothesis if p-value < 0.05

(fourth part) On the basis of the above findings, we cannot reject the null hypothesis. True

for remaining part ...........

to test of equality of more than two variances we generaly use bartlett's and levene's test , which gives ultimately F-value.

please specify what is H value
