Question 4

  1. Consider the following statements concerning the methodology of classical hypothesis testing:

    A. The decision to reject the null hypothesis is made when the p-value is less than alpha.
    B. The decision to reject Ho implies that the sample data used for the test must have been inappropriate and a different sample will always need to be re-selected.
    C. When the level of significance is decreased for a test where Ha specifies that the value of the population parameter has decreased, then the critical value for the test also decreases.

Which is true?Why?

The primary purpose of hypothesis testing is to attempt to reject the null hypothesis not to accept the alternative hypothesis. True False In hypothesis testing, a Type 1 error is failing to reject the null hypothesis when it is true. failing to reject the null hypothesis when it is false. rejecting the null hypothesis when it is true. rejecting the null hypothesis when it is false.

Which of the following statements about hypothesis testing is true? If the data provide sufficient evidence for the alternative hypothesis, then the conclusion is to reject H0. A hypothesis test provides a plausible range of values for a parameter. If the data provide sufficient evidence for the null hypothesis, then the conclusion is to reject H1. A hypothesis test uses sample data to determine which of two competing hypotheses is true. For a two-sided hypothesis test in which the test...

Questions D-F d) You conduct a hypothesis test for the population proportion. After you calculate the z test statistic, you find that your p-value = 0.059. Using alpha (α) = 0.05 level of significance, what is your decision regarding the null hypothesis? Choose from the following. - Reject the null hypothesis and reject the alternative hypothesis - Accept the null hypothesis - Do not reject the null hypothesis - Reject the null hypothesis and accept the alternative hypothesis e) You...

You will perform a Two Sample Hypothesis Test for Proportions. For the Hypothesis Test, make sure to report the following steps: Identify the null hypothesis, Ho, and the alternative hypothesis, Ha. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Find the critical value(s) and identify the rejection region(s). Find the appropriate standardized test statistic. If convenient, use technology. Decide whether to reject or fail to reject the null hypothesis. Interpret the decision in the context of the original...
