The null and alternative hypotheses are: H 0 : d 0 H 1 : P1 - P2 0 A sample of 90 observations from the first population indicated that X 1 is 73.

The null and alternative hypotheses are: 

H0: μd ≤ 0    

H1: P1 - P2 > 0

A sample of 90 observations from the first population indicated that X1 is 73. A sample of 144 observations from the second population revealed X2 to be 88. Use the 0.1 significance level to test the hypothesis. 

a.State the decision rule. (Round the final answer to 3 decimal places.)                     

H0 is (rejected or not) rejected if z > _______. 

b.Compute the pooled proportion. (Round the final answer to 2 decimal places.)   

 Pooled proportion _______   

c.Compute the value of the test statistic.(Negative answer should be indicated by minus sign. Round the final answer to 2 decimal places.)    

Test statistic  _______  

d.What is your decision regarding the null hypothesis?   

 H0 should (not be rejected or be rejected)

. 

e.Determine the p-value. (Round the final answer to 4 decimal places.)   

 p-value _______
