Twenty years ago, 49% 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. recent survey found that 222 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. 5% of the population size, and the sample Because npo (1-Po)=[ requirements for testing the hypothesis (Round to one decimal place as needed.) ▼10, the sample size is satisfied. the
