Twenty years ago, 52% 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 281 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=0.1 level of significance. *** Because npo (1-Po) = 199.7 less than 5% of the population size, and the sample can be reasonably assumed to be random, the 10, the sample size is requirements for testing the hypothesis are satisfied.

Imagine you are doing a Related-Samples t-test, and you are on Step Four of the hypothesis test. The study you are doing is testing whether there’s a significant difference between the anxiety of people before and after a final exam. The APA sentence is t(28) = 3.45, p < .05, d = 1.05. What is the correct set of conclusions that goes with this APA sentence? Group of answer choices Reject the H0, conclude that there IS a difference in anxiety, conclude based on effect size that the difference is small. Fail to Reject the H0, conclude that there IS a difference in anxiety. Reject the H0, conclude that there IS NOT a difference in anxiety, conclude based on effect size that the difference is small. Fail to Reject the H0, conclude that there IS NOT a difference in anxiety. Reject the H0, conclude that there IS a difference in anxiety, conclude based on effect size that the difference is large.

The Census Bureau's American Housing Survey has reported that 76 percent of families choose their house location based on the school district. You want to conduct a test of whether the population proportion really equals 0.76. Use a 0.10 level of significance and a sample of 440. The proportion of families in your sample that choose their home based on the school district was 0.78. a. State in statistical terms the null and alternative hypotheses. (2 points) b. Determine the appropriate test statistic. (z or t) (2 points) c. Determine the critical values. (2 points) d. Compute the test statistic. (2 points) e. Make a decision on the hypotheses. (which hypothesis is correct?) (2 points)
