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 240 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 = 0.01 level of significance. Because npo (1- V10, the sample size is Po) 5% of the population size, and the sample V the = requirements for testing the hypothesis V satisfied. (Round to one decimal place as needed.)
