There is a theory that people can postpone their death until after an important event. To test the theory, Phillips and King (1988) collected data on deaths around the Jewish holiday Passover. Of 1919 deaths, 922 died the week before the holiday and 997 died the week after. Test the theory and report and interpret the p-value.

Answer:

Step-by-step explanation:

We have to test the theory that people can postpone their death until after an important event.

Proportion of deaths before holiday p1= [tex]\frac{922}{1919} =0.4805[/tex]

Proportion of deaths after holiday p2=[tex]\frac{997}{1919} =0.5195[/tex]

Set up hypotheses as

H0: p1 =p2

Ha: p1 <p2

(Left tailed test at 5% sign level)

z=-1.7757

p value=0.03754

Since p < 0.05 we reject null hypothesis

p value is  probability of obtaining results as extreme as the observed results of a statistical hypothesis test, assuming that the null hypothesis is correct. .
