solution

Refer to the previous exercise about the study of the
relationship between sleep apnea and hypertension. Suppose that the observed
cell counts were actually three times as big as those reported in the original
study. For parts (a)–(c): How, if at all, would the values of the following
change?

a.      
The expected cell counts: Increase Decrease Stay the same

 b. The p-value: Increase Decrease
Stay the same

c. The chi-square statistic:
Increase Decrease Stay the same

       d. Would the evidence in support of an association
between sleep apnea and hypertension for people such as the ones in the study
be stronger or weaker compared to the original study? Explain how you are
deciding.
