Question Help Twenty years ago, 48% 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 215 of 750 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 a = 0.1 level of significance. Because npo (1- Po = V 10, the sample size is 5% of the population size, and the sample the requirements for testing the hypothesis (Round to one decimal place as needed.) satisfied. What are the null and alternative hypotheses? Ho: (Type integers or decimals. Do not round.) versus H,: Find the test statistic. Zp =(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. O A. Since P-value a, do not…
