A poll in June 2020 found that 83% of American parents believe that virtual learning instead of in- person learning widens the equity gap for students. A later poll in October 2020 asked 1025 American parents if they believe virtual learning instead of in- person learning widens the equity gap for students, and found that 820 believe that yes, virtual learning instead of in-person learning widens the equity gap for students. Does this mean that the proportion of American parents, who believe that virtual learning instead of in-person learning widens the equity gap for students, has decreased? Test at the 10 % significance level. State the hypotheses. Ho: p (? HA: p (? Calculate the sample proportion. Round to four decimal places. p = Calculate the test statistic. Round to two decimal places. Find the p-value. Give to four decimal places. p-value = State your decision. Since the p-value is less than 0.1, fail to reject Ho. Since the p-value is less than 0.1, reject Ho. Since the p-value is greater than 0.1, fail to reject Ho. Since the p-value is greater than 0.1, reject Ho. Interpret the results.
