The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) a = 0.01, (b) a = 0.05, and (c) a = 0.10. P= 0.0961 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? O A. Reject Ho because the P-value, 0.0961, is greater than a =0.01. O B. Fail to reject Ho because the P-value, 0.0961, is greater than a = 0.01. O C. Reject Ho because the P-value, 0.0961, is less than a = 0.01. O D. Fail to reject Ho because the P-value, 0.0961, is less than a = 0.01. (b) Do you reject or fail to reject Ho at the 0.05 level of significance? O A. Fail to reject Ho because the P-value, 0.0961, is less than a = 0.05. O B. Fail to reject Ho because the P-value, 0.0961, is greater than a = 0.05. O C.

The term error is used two different ways in the context of a hypothesis test. First, there is the concept of standard error, and, second, there is the concept of a Type I error.a. What factor can a researcher control that will reduce the risk of a Type I error? Explain the logic.b. What factor can a researcher control that will reduce the standard error? Explain the logic.

A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
Hypothesis Test: Perform the specified hypothesis test. Be sure to include your statistical andin-context conclusion statements. In 1994, 52% of parents with children in high school felt it was a serious problem that high schoolstudents were not being taught enough math and science. A recent survey found that 512 of 1000 parentswith children in high school felt it was a serious problem that high school students were not being taughtenough math and science. Do parents feel different today than they did in 1994? Use the α = 0.005significance level.

Perform a hypothesis test for a population mean and for a population proportion A group of psychologists commented that less than 57% of them help children to enjoy reading to improve their intelligence. An investigation was conducted to find out if this is true in a certain school zone. 210 psychologists were randomly chosen and interviewed to detect whether, by developing their work in psychology, they help children to enjoy reading to improve their intelligence; It was found that 105 psychologists do help children. Perform the hypothesis test with alpha of 10%.
