In a recent poll, 1090 randomly selected adults were asked whether they approve of labor unions; 62% said yes. a. In 1936, about 68% of adults approved of labor unions. At the 10% significance level, do the data provide sufficient evidence to conclude that the percentage of adults who approve of labor unions has decreased since 19367 b. In 1963, roughly 64% of adults approved of labor unions. At the 10% significance level, do the data provide sufficient evidence to conclude that the percentage of adults who approve of labor unions has decreased since 1963?

What are the hypotheses for the one-proportion z-test? Hop= : H. DY (Type integers of decimals.) What is the test statistic? z= (Round to two decimal places as needed.) Identify the critical value(s) (Round to two decimal places as needed.) What is the correct conclusion for the hypothesis test? 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 Ho; the data do provide sufficient evidence to conclude that the percentage of adults who approve of labor unions has decreased since 1938. O C. Reject Ho: the data do not provide sufficient evidence to conclude that the percentage of adults who approve of labor unions has decreased since 19036. O D. Reject Ho: the data do provide sufficient evidence to conclude that the percentage of adults who approve of labor unions has decreased since 1936. b.
