Twenty years ago, 48% of parents of children in high school fell it was a serious problem that high school students were not being taught enough math and science. A recent survey found that 192 of 700 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.| level of significance. Because npo (1-PD) = 10, the sample size is 5% of the population size, and the sample the requirements for testing the hypothesis satisfied (Round to one decimal place as needed.)
