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 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=: Hạ: p (Type integers or decimals.) What is the test statistic? (Round to two decimal places as needed.) z= Identify the P-value. The P-value is (Round to four decimal places as needed.) What is the correct conclusion for the hypothesis test? O A. 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 1936. O B. 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 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 1936. 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.

Transcribed Image Text:In a recent poll 1089 randomly selected adults were asked whether they approve of labor unions; 59% said yes. In 1936, about 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 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=; Ha: p
(Type integers or decimals.)
What is the test statistic?
(Round to two decimal places as needed.)
Identify the P-value.
The P-value is.
(Round to four decimal places as needed.)
What is the correct conclusion for the hypothesis test?
O A. 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 1936.
B. 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.
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 1936.
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.
