Consider the observed frequencies. Observed Frequencies (fij;) Populations Response 1 2 3 Yes 132 132 78 No 118 168 122 (a) Compute the sample proportion of Yes responses for each population. (b) Use the multiple comparison procedure to determine which population proportions differ significantly. Use a 0.05 level of significance. The sample proportion, p, of the Yes responses for each population will be calculated using the Yes and No responses for the respective population as follows. sample proportion = Recall the given data. yes responses yes and no responses Observed Frequencies (fi;) Populations Response 1 2 3 Yes 132 132 78 No 118 168 122 Let p represent the sample proportion of Yes responses for population 1, P2 represent the sample proportion of Yes responses for population 2, and 3 represent the sample proportion of Yes responses for population 3. Find the sample proportions. P1 = 132 + 118 = = 132 + 168 = P3 = 78 + 122
