Twenty years ago, 47% of parents of children in high school felt it was a serious problem that high school students were not being taught enough ma and science. A recent survey found that 293 of 900 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- Po) =U 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.)
