Question 21 (1 Point You conduct a hypothesis test of How = 225 versus Hau > 225 using a computer and get the following results: Z - 2.085 p-value = 0.029 The significance level for this test is alpha-0.05, so you decide to reject the null hypothesis. Which of the following statements is true? (Select all that apply) A The p-value for a two-tailed test would be half the current p-value. B if this test was two-tailed instead of one-tailed,...
You are asked to conduct a simulation and run a hypothesis test at a significance level of 0.10. Based on your simulation, you find that the p-value is 0.051. What does this mean for your hypothesis test? 1. Since the p-value is greater than the significance level, you must fail to reject the null hypothesis. 2. Since the p-value is less than the significance level, you must fail to reject the null hypothesis. 3. Since the p-value is less than...
You conduct a hypothesis test for the population mean. After you calculate the t test statistic, you find that your p-value = 0.04. Using alpha (a) = 0.01 level of significance, what is your decision regarding the null hypothesis? (either reject Ho and accept Ha, or fail to reject Ho)
37. Use the following information for questions 37-38: Suppose you conduct a hypothesis test to determine whether or not the average age difference between married couples is less than 5 years. You conduct this test at the 0.10 significance level and come to the conclusion that 0.01 < p-value < 0.02. What is the correct decision? a. Fail to Reject the Null Hypothesis b. Reject the Null Hypothesis c. Accept the Null Hypothesis d. Accept the Alternative Hypothesis

Suppose a hypothesis test is conducted using a significance or alpha level of 0.05, and the null hypothesis is rejected. This means that? A we would also reject the null hypothesis if the significance level had been 0.10 instead of 0.05. B the p-value was greater than 0.05. C we would also reject the null hypothesis if the significance level had been 0.01 instead of 0.05. D All answer options are correct.
(a) Suppose the null and alternative hypothesis of a test are: H0: μ= 9.7 H1: μ >9.7 Then the test is: left-tailed two-tailed right-tailed (b) If you conduct a hypothesis test at the 0.02 significance level and calculate a P-value of 0.07, then what should your decision be? Fail to reject H0 Reject H0 Not enough information is given to make a decision
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...
Test the claim that the proportion of people who own cats is smaller than 70% at the 0.10 significance level. The null and alternative hypothesis would be: H 0 : μ = 0.7 H 1 : μ ≠ 0.7 H 0 : μ ≥ 0.7 H 1 : μ < 0.7 H 0 : p ≤ 0.7 H 1 : p > 0.7 H 0 : p ≥ 0.7 H 1 : p < 0.7 H 0 : p =...
You are completing a hypothesis test. You know the following items: The test is a two-tailed test. The critical value for the test is + 2.763 The standardized test statistic is -2.768 Assume the population is normally distributed. Decide whether to reject or fail to reject the null hypothesis.
