a. Choose the appropriate alternative hypothesis to test if the population proportions differ.
O All population proportions differ from 0.20.
O Not all population proportions are equal to 0.20.
b. Calculate the value of the test statistic. (Round intermediate calculations to at least 4 decimal places and final answer to 3
decimal places.)

c. Find the p-value.
O pvalue 20.10
O 0.05 S p-value <0.10
O 0.025 B p-value < 0.05
O 0.01B p-value <0.025
O pvalue <0.01
d. Can we conclude at the 1% significance level that the population proportions are not equal?
O Yes, since the p-value is more than the significance level.
O No, since the p-value is more than the significance level.
O Yes, since the p-value is less than the significance level.
O No, since the p-value is less than the significance level.
