The sample size is less than 5% of the population size for each sample. F. The data come from a population that is normally distributed. Identify the null and alternative hypotheses for this test. Let p1 represent the population proportion of 1950 adults who were total abstainers and p2 represent the population proportion of recent adults who were total
abstainers. Determine the null and alternative hypotheses. Find the test statistic for this hypothesis test. 1.46 (Round to two decimal places as needed.)
Determine the P-value for this hypothesis test.
0.144 (Round to three decimal places as needed.) Interpret the P-value. If the population proportions are i one would expect a sample difference proportion V the one observed in about out of 100 repetitions of this experiment.
(Round to the nearest integer as needed.) Enter your answer in the answer box and then click Check Answer. @
