In 2011, a U.S. Census report determined that 52% of college students are working students. A researcher thinks this percentage has changed and surveys 135 college students. The researcher reports that 72 of the 135 are working students. Is there evidence to support the researcher's claim at the 1% significance level? a. Determine the null and alternative hypotheses. Ho: p = 52 H₁: p ±✰ 52 and enter the value.) (Select the correct symbol b. Determine the test statistic. Round to two decimal places. z = 0.33 c. Find the p-value. Round to four decimal places. p-value= = 0.7414 d. Are the results statistically significant? Fail to reject the null hypothesis. Reject the null hypothesis. e. Write the conclusion. There is sufficient evidence to support the claim that the percentage of working college students has changed. There is not sufficient evidence to support the claim that the percentage of working college students has changed.
