help with stats

Twenty years ago, 53% of parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. A recent survey found that 284 of 800 parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. Do parents feel differently today than they did twenty years ago? Use the = 0.1 level of significance. Because npo (1 - Po) 10, the sample size is 5% of the population size, and the sample the requirements for testing the hypothesis satisfied. %D (Round to one decimal place as needed.) What are the null and alternative hypotheses? Họ: (Type integers or decimals. Do not round.) versus H,: Find the test statistic. (Round to two decimal places as needed.) Find the P-value. P-value = (Round to three decimal places as needed.) Determine the conclusion for this hypothesis test. Choose the correct answer below. A. Since P-value > a, reject the null hypothesis and conclude that there is not sufficient evidence that parents feel differently today. B. Since P-value < a, reject the null hypothesis and conclude that there is sufficient evidence that parents feel differently today. C. Since P-value < a, do not reject the null hypothesis and conclude that there is sufficient evidence that parents feel differently today. D. Since P-value > a, do not reject the null hypothesis and conclude that there is not sufficient evidence that parents feel differently today.
