When z-test statistics is +5, at 2% level of significance for H0: µ = 75, what is the decision regarding the null hypothesis
Z value =5
Z critical value at 2% level of significance=2.57
Since Z value>Z critical
Thus we reject our null hypothesis.

7. When z-test statistics is +5, at 2% level of significance for H0: µ = 75, what is the decision regarding the null hypothesis
4. It is desired to test H0 : µ = 20 Vs H1 : µ < 20, on the basis of a random sample of size 64 from normal distribution with population standard deviation σ = 2.4. The sample mean and sample standard deviation are found to be 19.5 and 2.5, respectively. (a) Test the hypothesis at α = 0.05. Compute the test statistics, critial regions, and perform the test. Will the result be difference if α is changed to...

A sample of 14 from an approximately normal population is used to test H0: µ = 5 versus H1: µ > 5. If the p-value of this test is 0.0329, which of the following is the correct decision and conclusion at the α = 0.05 level? a)Reject the null hypothesis concluding that there is no evidence the true mean is larger than 5. b)Do not reject the null hypothesis concluding that there is evidence the true mean is larger than 5. c)Reject...
In #13-16, use the following information. At the 0.01 level of significance, test the claim that µ ≤ 25.5 cm. Sample data consist of 25 observations, for which x = 27.3 cm and s = 3.7 cm. 13. Give the null hypothesis in symbolic form. (a) H0 : p = 27.3 (b) H0 :x = 27.3 (c) H0 :µ ≤ 25.5 (d) H0 :σ = 3.7 (e) H0 :µ = 27.3 14. Determine the appropriate test statistic. (a) z =...
In order to test the following hypotheses at an α level of significance H0: μ ≤ 800 Ha: μ > 800 the null hypothesis will be rejected if a) the test statistic z ≥ zα. b) the test statistic z < zα. c) the test statistic z < −zα. d) the test statistic z = α.
