QUESTION 16 5 points Save Answer TRUE OR FALSE: In order to reject the null hypothesis, the p-value (i e., Sig. in SPSS) must be less than the alpha level. O True O False
I. IF we do not reject the null hypothesis when the alternative hnthsinthen we have made Type B error (b) Correct decision (e) Type I error (a) Type I1 error Use for Problems 2 and 3.

1. When we reject the null hypothesis, we are saying that… we have proven the alternative hypothesis to be true we have proven the null hypothesis to be false our sample is too unlikely to have been produced by the null distribution our sample had a mean approximately the same as the population our sample had a standard deviation smaller than the population
O A. Because the p-value is less than a, we reject the null hypothesis and conclude that the average det load is equal to $17,000 O B. Because the p-vakus is greafer than a we fail to reject the nu ○ C. Because the p-value is greater than a we fail to reject the nul hypothesis and cannot co clude that he OD. Because the pvalue is lesse an Suppose that the Department of Education would like to test the...
Determine the decision criterion for rejecting the null hypothesis in the given hypothesis test, i.e., describe the values of the test statistic that would result in rejection of the null hypothesis. We wish o compare he means of two populations using paired observations. Suppose hat d: 3 12 sd 2. and n : 8 and that you wish to est e h pothesis below at he 1 % level of signiticance hat decision le ou d ou u O A....
Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. A test of sobriety involves measuring the subject's motor skills. A study of n = 20 randomly selected sober subjects take the test and produce a mean score of X = 41.0, and we know that o = 3.7. At the 0.01 level of significance, test the claim that the true mean score for all sober subjects is...
Question 5 2 pts Which of the following statements is true? (a) we reject a null hypothesis if the p-value of the test is smaller than the level of the significance a. (b) we accept a null hypothesis if the p-value of the test is smaller than the level of the significance a. (c) we reject a null hypothesis if the p-value of the test is larger than the level of the significance a. . (a) . (b) . (c)
On the basis of sample information, we either "accept the null hypothesis" or "reject the null hypothesis." True O False
1. You want to test whether you can reject the null hypothesis that a population mean is greater than or equal to 10. To do this, you collect a random sample of size 500 from the population, and you calculate that the sample mean and sample standard deviation are 8.6 and s, respectively. Which of the following is true? a. If s is any value between 11 and 13, you can reject the null hypothesis at the 5% significance level....
Question 21 (4 points) For a hypothesis test about a population proportion or mean, if the level of significance is less than the p- value, the null hypothesis is rejected. (Ch10) True False Question 22 (4 points) Everything else being constant, increasing the sample size decreases the probability of committing a Type II error. (Ch10) True False The power of a statistical test is the probability of not rejecting the null hypothesis when it is true. (Ch10) True False Question...
