In a recent poll 1001 randomly selected adults were asked whether they approve of labor unions; 62% said yes. In 1936, about 66% of adults approved of labor unions. At the 5% significance level, do the data provide sufficient evidence to conclude that the percentage of adults who approve of labor unions has decreased since 1936? Use the one-proportion z-test to perform the appropriate hypothesis test, after checking the conditions for the procedure. What are the hypotheses for the one-proportion z-test? Ho: p =: H; P (Type integers or decimals.) What is the test statistic? z= (Round to two decimal places as needed.) Identify the critical value (S). (Round to three decimal places as needed.) What is the correct conclusion for the hypothesis test? O A. Do not reject Ho ; the data do not provide sufficient evidence to conclude that the percentage of adults who approve of labor unions has decreased since 1936. O B. Do not reject H : the data do provide sufficient evidence to conclude that the percentage of adults who approve of labor unions has decreased since 1936. O C. Reject Ho; the data do provide sufficient evidence to conclude that the percentage of adults who approve of labor unions has decreased since 1936. O D. Reject Ho; the data do not provide sufficient evidence to conclude that the percentage of adults who approve of labor unions has decreased since 1936
