A. .81

B. .80

D. .83

*Hint A preference for a day to take sick leave will be indicated by dependence.

7. Continuing, determine the critical value at the significance level of .05 using one of

-Table Chi Square Table

• = CHISQ.INV.RT
• = CHISQ.INV
• =CHIINV() to find the critical value.

The critical value is:

A. 11.070

B. 12.592

C. 1.145

D. 1.635

8. Continuing, find the pvalue using the chi square statistic in a) and one of the EXCEL function CHISQ. DIST.RT, =CHISQ.DIST, or =CHIDIST().

The pvalue is:

A. 0.977

B. 0.023

C. 0.992

D. 0.936

*Hint: You can check your results by comparing the results of multiple methods

9. Comparing the chi square statistic in a) to the critical value b), or the pvalue in c) to ?, is it indicated that employees have a tendency to use Monday as a sick day?
