hello I need help with the following

Question Help A 2018 poll of 3646 randomly selected users of a social media site found that 2489 get most of their news about world events on the site. Research done in 2013 found that only 45% of all the site users reported getting their news about world events on this site. a. Does this sample give evidence that the proportion of site users who get their world news on this site has changed since 2013? Carry out a hypothesis test and use a 0.05 significance level. b. After conducting the hypothesis test, a further question one might ask is what proportion of all of the site users get most of their news about world events on the site in 2018. Use the sample data to construct a 95% confidence interval for the population proportion. How does your confidence interval support your hypothesis test conclusion? a. State the null and alternative hypotheses. Let p be the proportion of site users who get their world news on the site. Ho: P = 0.45 Ha: P 0.45 (Type integers or decimals. Do not round.) Compute the z-test statistic. z= (Round to two decimal places as needed.) Compute the p-value. p-value = (Round to three decimal places as needed.) Reject Ho or do not reject Ho and interpret the conclusion. Choose the correct answer below. O A. Do not reject Ho. The percentage is significantly different from 45%. O B. Do not reject Ho. The percentage is not significantly different from 45%. O C. Reject Ho. The percentage is significantly different from 45%. Click to select your answer(s).
