What is the power of a test? Select all that apply. a.The probability that a significance test will pick up on the fact that the true value is different from the null. b.The probability of incorrectly rejecting the null when it's true. c.The probability of incorrectly failing to reject the null when it's false. d.The probability of correctly rejecting the null when the null is false. e.The probability of avoiding a type 2 error

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.
2. The steps of hypothesis testing You intend to draw a random sample in order to test a hypothesis about an unknown population mean. You will use a hypothesis test. A description of each of the steps of a hypothesis test follows, but they may be specified in the incorrect order. Specify the correct order of the steps. Determine the null and alternative hypotheses. Select a level of significance. Make a decision about the unknown population. Select a sample and compute the z-score for the sample mean.
Question Help A random sample of 870 births included 426 boys. Use a 0.10 significance level to test the claim that 50.6% of newborn babies are boys. Do the results support the belief that 50.6% of newborn babies are boys?
