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?

Days Worked Last Year by 23 Employees
Department	Days Worked
Budgets (5 workers)	259	258	268	248	259
Payables (10 workers)	204	272	217	240	255	216	266	241	240	230
Pricing (8 workers)	238	260	235	253	230	244	242	250

Based on the given hypotheses, choose the correct option H<₀: ₁ = ₂ = ₃ H₁: Not all the means are equal = .05

multiple choice 1

• Reject the null hypothesis if p-value > 0.05

• Reject the null hypothesis if p-value < 0.05

On the basis of the above findings, we cannot reject the null hypothesis. multiple choice 2

• True

• False

Based on the given hypotheses, choose the correct option. H₀: ²₁ = ²₂ = ²₃ H₁: Not all the variances are equal = .05 multiple choice 3

• Reject the null hypothesis if H > 8.38

• Reject the null hypothesis if H < 8.38

Calculate the value of H_calc. (Round your answer to 2 decimal places.) H_calc On the basis of the above-determined H_calc, we fail to reject the null hypotheses. multiple choice 4

• FALSE

• TRUE
