Step 2 Now that we know Do = 0 and have the following data, the z test statistic can be found. Recall the given data. Sample 1 Sample 2 ni = 70 n2 = 60 *1 = 102 x2 = 104 91 = 8.6 02 = 7.8 2 + Find the value of the test statistic, rounding the result to two decimal places. (x - x) - Do Z= 2 02 ni n2 (102 - 104) - 0 (8.62 70 7.82 + 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 yes responses yes and no responses Recall the given data Observed Frequencies (3) Populations Response 1 2 144 M 90 No 106156 110 Yes Let , represent the sample proportion of Yes responses for population 1., represent the sample proportion of Yes responses for population 2, and represent the sample proportion of Yes responses for population 3. Find the sample proportions. P- 144 + 100 P 144+ 150 90 + 110 Submit You cannot come back
