Use the sample data below to test the hypotheses

Ho: p1 = p2 = p3

Ha : Not all population proportions are the same

Populations
Response 1 2 3
Yes 150 150 93
No 100 150 107

where pi is the population proportion of yes responses for population i. Using a .05 level of significance.

a. Compute the sample proportion for each population. Round your answers to two decimal places.

p1 = (___)
p2 = (___)
p3 = (___)

b. Use the multiple comparison procedure to determine which population proportions differ significantly. Use a 0.05 level of significance. Round pi, pj and difference to two decimal places. Round critical value to four decimal places.

Comparison p i p j |Absolute| Difference n i n j Critical
Value
Significant Diff > CV
1 vs 2 (__) (__) (___) (__) (__) (__) Yes/No
1 vs 3 (__) (__) (___) (__) (__) (__) Yes/No
2 vs 3 (__) (__) (___) (__) (__) (__) Yes/No
