Twenty years ago, 56% 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 308 of 800 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= 0.05 level of significance. Because npo (1-Po) = 10, the sample size is (Round to one decimal place as needed.) 5% of the population size, and the sample ▼the requirements for testing the hypothesis satisfied.

Question
Twenty years ago, 56% 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 308 of 800 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 α = 0.05 level of significance. Because npo (1-Po) 10, the sample size is (Round to one decimal place as needed.) = 5% of the population size, and the sample the requirements for testing the hypothesis satisfied.

Twenty years ago, 56% 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 308 of 800 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 α = 0.05 level of significance. Because npo (1-Po) = 197.1 > 10, the sample size is (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho: P 0.56 versus H₁: р (Type integers or decimals. Do not round.) Find the test statistic. # 0.56 Zo -9.97 (Round to two decimal places as needed.) = Find the P-value. P-value = (Round to three decimal places as needed.) less than 5% of the population size, and the sample can be reasonably assumed to be random, the requirements for testing the hypothesis are satisfied.
