I need help solving 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 254 of 800 parents of children in high school felt it was a seriousproblem that high school students were not being taught enough math and science.

Given that, x = 254,n = 800 Because np0(1-p0) =800×0.48×(1-0.48)=199.7>10, the sample size is less than 5% of the population size and the sample can be reasonably assumed to be random and the requirements for testing the hypothesis are satisfied. The sample proportion is,The value of test statistic is, Critical values: By using the Z-table, the critical value at 90% confidence level for two tailed test is, Z0.10/2=±1.65 Since the test statistic value (-9.20) less than critical value (-1.65), then reject the null hypothesis Conclusion: Reject the null hypothesis. There is sufficient evidence to conclude that the number of who feel that students are not being taught enough math and science is significantly different from 20 years ago.
