Twenty years ago, 48% 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 302 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 = 0.05 level of significance. Click here to view the standard normal distribution table (page 1).

Because npo (1-Po) = 224.6 >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 (Round to one decimal place as needed.)
