Extracted text: Twenty years ago, 54% 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 314 of 850 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) = 211.1 (Round to one decimal place as needed.) > 10, the sample size is less than 5% of the population size, and the sample can be reasonably assumed to be random, the requirements for testing the hypothesis satisfied. are What are the null and alternative hypotheses? = 0.54 versus H,: p * 0,54 Ho: p (Type integers or decimals. Do not round.) Find the test statistic. Zo = (Round to two decimal places as needed.)
