A hypothesis will be used to test that a population mean equals 12 against the alternative that the population mean is less than 12 with known variance o. What is the critical value for the test statistic Zo for the significance level of 0.010? Round your answer to two decimal places (e.g. 98.76). 21-a =

Assume that the population variance is unknown. We test the hypothesis that Ho: µ=5 against the alternative that it is not at a level of significance of 5% and a sample size of n=151. We calculate a test statistic = -1.976. The p-value of this hypothesis test is approximately ? . (Write your answer out to two decimal places. In other words, write 5% as 0.05.)

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 the rejection of the null hypothesis. Suppose you wish to test the claim that , u d the mean value of the differences d for a population of paired data, is greater than 0. Given sample of n= 15 and the significance of level of a=0.01, what criterion would be used for rejecting the...

1. It is desired to test the null hypothesis u = 40 against the alternative hypothesis u < 40 on the basis of a random sample from a population with standard deviation 4. If the probability of a Type I error is to be 0.04 and the probability of Type II error is to be 0.09 for u = 38, find the required size of the sample.

Your research supervisor wants you to test the null hypothesis H0: μ = 25 against the one-sided alternative hypothesis Ha: μ < 25. The population has a normal distribution with a variance of 16. You are told to use a sample size of 100 and a rejection region of . State the probability of a Type II error for this test of significance to four digits to the right of the decimal point under the alternative hypothesis that μ = 24.

Alejandra is using a one-sample t-test to test the null hypothesis Ho: u = 10.0 against the alternative H1: 4 < 10.0 using a simple random sample of size n = 10. She requires her results to be statistically significant at level a = 0.10. Determine the maximum value of t that will reject this null hypothesis. You may find this table of t-critical values useful. If you are using software, you may find this catalog of software guides useful....
