Twenty years ago, 57% 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 244 of 700 parents of children in 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 = 0.1 level of significance. Because npo (1- pPo) =U 10, the sample size is 5% of the population size, and the sample V the requirements for testing the hypothesis V satisfied (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho (Type integers or decimals. Do not round,) versus H,: Find the test statistic. Zn = (Round to two decimal places as needed.) Find the P-value. P-value = (Round to three decimal places as needed.) Determine the conclusion for this hypothesis test. Choose the correct answer below. O A. Since P-value < a, do not reject the null hypothesis and conclude that there is sufficient evidence that parents feel differently today. O B. Since P-value > a, reject the null hypothesis and conclude that there is not sufficient evidence that parents feel differently today. OC. Since P-value > a, do not reject the null hypothesis and conclude that there is not sufficient evidence that parents feel differently today. O D. Since P-value < a, reject the null hypothesis and conclude that there is sufficient evidence that parents feel differently today.

Question
Transcribed Image Text:Twenty years ago, 57% 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 244 of 700 parents of children in h
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= 0.1 level of significance.
Because npo (1-pPo) =U 10, the sample size is
V 5% of the population size, and the sample
the requirements for testing the hypothesis
satisfied.
(Round to one decimal place as needed.)
What are the null and alternative hypotheses?
V versus H,:
Ho:
(Type integers or decimals. Do not round.)
Find the test statistic.
Z, = (Round to two decimal places as needed.)
Find the P-value.
P-value = (Round to three decimal places as needed.)
Determine the conclusion for this hypothesis test. Choose the correct answer below.
O A. Since P-value <a, do not reject the null hypothesis and conclude that there is sufficient evidence that parents feel differently today.
O B. Since P-value > a, reject the null hypothesis and conclude that there is not sufficient evidence that parents feel differently today.
OC. Since P-value> a, do not reject the null hypothesis and conclude that there is not sufficient evidence that parents feel differently today.
O D. Since P-value <a, reject the null hypothesis and conclude that there is sufficient evidence that parents feel differently today.
