Extracted text: Twenty years ago, 52% 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 281 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 a = 0.05 level of significance. Because npo (1- Po) = > 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 are satisfied. (Round to one decimal place as needed.)
