HI PLEASE HELP AND ANSWER ALL CORRECTLY THANKS

A magazine is considering the launch of an online edition. The magazine plans to go ahead only if it is convinced that more than 20% of current readers would subscribe. The magazine contacted a simple random sample of 500 current subscribers, and 122 of those surveyed expressed interest. What should the magazine do? . What are the null and alternative hypotheses? A. Ho: p= 0.2 vs. HA:p>0.2 OB. Ho: p<0.2 vs. Ha: p=0.2 O C. Ho:p>0.2 vs. Ha: p=0.2 OD. Ho: P = 0.2 vs. Hap<0.2 What is the value of the test statistic? O A. The test statistic is (Round to two decimal places as needed.) OB. The assumptions and conditions are not met, so the test cannot proceed. What is the test statistic is and what is the P-value of the test statistic? Some people are concerned that new tougher standards and high-stakes tests adopted in many states have driven up the high school dropout rate. An organization reported that the high school dropout rate for a very recent year was 6.3%. One school district whose dropout rate has always been very close to the national average reports that 109 of their 1598 high school students dropped out last year. Is this evidence that their dropout rate may be increasing? Explain. Consider an event to be rare if its probability of occurring is less than 0.01. Identify the appropriate hypotheses. Let p be the population proportion of high school students who drop out in a year. Ho: P = 0.063 HAD > 0.063 (Type integers or decimals. Do not round.) The test statistic for this test is (Round to two decimal places as needed.) What is the P-value
