i am using minitab to solve the problem.
steps :-
copy the data in minitab 
stat 
table 
chi
square test for association 
select summarized data in a two way table from the drop down menu
in
columns containing the table select 1,2,3 
in
rows select responses
ok.
*** SOLUTION ***
the calculated test statistic = 9.249 .
*** if you have any doubt regarding the problem ,please write it in the comment box...if satisfied,please UPVOTE.

Consider the following competing hypotheses and accompanying sample data. Ho: Pi-P2 = 0.20 HA P - P2 = 0.20 X2 = 130 X1 = 150 n = 250 m2 = 400 a. Calculate the value of the test statistic. b. Calculate the p-value. c. At the 5% significance level, what is the conclusion to the test? Can you conclude that the difference between the population proportions differs from 0.20? d. Repeat the analysis with the critical value approach.
