In hypothesis testing, does choosing between the critical value method or the P-value method affectyour conclusion? Explain.Choose the correct answer below.OA. Yes, because the critical value method uses critical value(s) to identify the rejection region(s). The P-valuemethod compares the P-value with the level of significance aO.B. No, because both involve comparing the test statistic's probability with the level of significance.OC. Yes, because the critical value method is more accurate than the P-value method.OD. Yes, because the P-value method is more accurate than the critical value method.OE. No, because both methods involve comparing the standardized test statistic with the rejection region(s).

Median household income in a particular county is $46,250. A researcher is interested to see whether students at the county community college have a median household income lower than the county overalI. She selects 15 students at random and determines that 12 have a household income below the county median, one has an income equal to the county median, and two have a household income above the county median. She wishes to conduct her test using the 0.05 significance level. What is the decision rule? Multiple Choice Reject Ho if the number above the median is <3 or 28. Reject Ho if the number above the median is <3. Reject Ho if the number above the median is <2 or 210. Reject Ho if the number above the median is <2.

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
The critical value in a hypothesis test Multiple Choice depends on the value of the test statistic. is calculated from the sample data. separates the acceptance and rejection regions. usually is .05 or .01 in most statistical tests.

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.
The table below includes results from polygraph (lie detector) experiments conducted by researchers. In each case, it was known if the subjected lied or did not lie, so the table indicates when the polygraph test was correct. Use a 0.05 significance level to test the claim that whether a subject lies is independent of the polygraph test indication. Do the results suggest that polygraphs are effective in distinguishing between truth and lies? Determine the test statistic. (Round ofd to 3 decimal places) Find the P-Value What is the conclusion? (In case you are using excel, I will appreciate if you explain the steps of finding the test statistic and the P-value....But this is not a must)
