6 – Test Statistic LEARNING OBJECTIVE: Determine whether to reject a null hypothesis from a given p-value and significance level. BOOO > Select the correct statement. a.) Given a p-value of 0.01, and a significance level of 5%, you should reject the null hypothesis. b.) Given a p-value of 0.08, and a significance level of 2%, you should reject the null hypothesis. c.) Given a p-value of 0.06, and a significance level of 5%, you should reject the null hypothesis. d.) Given a p-value of...

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....

The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject H when the level of significance is (a) a= 0.01, (b) a 0.05, and (c) a0.10. P 0.0749 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? O A. Reject H because the P-value, 0.0749, is greater than a=0.01 O B. Fail to reject Ho because the P-value, 0.0749, is less than a = 0.01 O C. Reject...

Assume a researcher published a paper rejecting a null hypothesis at the 1% level of significance (that is, α = 0.01), which of the following statements is true? The finding may not be significant since it was not tested at an alpha level of 0.05 You cannot make any assumptions about the alpha at the 5% level without first calculating the value from the published data It is 5 times as likely the null hypothesis would be accepted at the...

State the decision to retain or reject the null hypothesis for each of the following F-tests at a 0.05 level of significance. (a) F(3, 28) = 3.37 Retain the null hypothesis. Reject the null hypothesis. (b) F(2, 33) = 3.09 Retain the null hypothesis. Reject the null hypothesis. (c) F(1, 120) = 4.07 Retain the null hypothesis. Reject the null hypothesis. (d) F(2, 60) = 3.11 Retain the null hypothesis. Reject the null hypothesis.

QUESTION 49 Assume a researcher published a paper rejecting a null hypothesis at the 1 % level of significance (that is, alpha-001). O a. The finding may not be significant since it was not tested at an alpha level of 0.05 b. You will also reject the null hypothesis at the 5% level of significance since alpha level of 0.01 is a more stringent test ] c. You cannot make any assumptions about the alpha at the 5% level without...
