- Hypotheses and parameters As in Exercise 1, for each ofthe following situations, define the parameter and write thenull and alternative hypotheses in terms of parameter values.a) Seat-belt compliance in Massachusetts was 65% in2008. The state wants to know if it has changed.b) Last year, a survey found that 45% of the employeeswere willing to pay for on-site day care. The companywants to know if that has changed.c) Regular card customers have a default rate of 6.7%.A credit card bank wants to know if that rate isdifferent for their Gold card customers.V Based on advancements in drug therapy, a pharmaceutical company is developing Resithan, a new treatment for depression. A medical researcher for the company is studying the effectiveness of Resithan as compared to their existing drug, Exemor. A random sample of 414 depressed individuals is selected and treated with Resithan, and 191 find relief from their depression. A random sample of 557 depressed individuals is independently selected from the first sample and treated with Exemor, and 213 find relief from their depression. Based on the medical researcher's study can we conclude, at the 0.05 level of significance, that the proportion p₁ of all depressed individuals taking Resithan who find relief from depression is greater than the proportion p₂ of all depressed individuals taking Exemor who find relief from depression?

Possible outcomes of a hypothesis test The following table depicts the four possible outcomes of a hypothesis test: The researcher makes a correct decision [either by correctly rejecting the null hypothesis (H₀) or correctly not rejecting the null hypothesis], makes a Type I error, or makes a Type II error. In each of the following boxes, select the description that matches the outcome. Decision Truth H₀ False H₀ True Reject H₀ Outcome A Outcome B Do not reject H₀ Outcome C Outcome D The probability of a Type I error is , and the probability of a Type II error is .
- Which of the following is NOT true for conducting a hypothesis test for independence between the row variable and column variable in a contingency table? Question content area bottom Part 1 Choose the correct answer below. A. The number of degrees of freedom is (r−1)(c−1), where r is the number of rows and c is the number of columns. B. The null hypothesis is that the row and column variables are independent of each other. C. Tests of independence with a contingency table are always right-tailed. D. Small values of the χ2 test statistic reflect significant differences between observed and expected frequencies.In a recent study of a random sample of 113 people, 92 reported dreaming in color. In the 1940’s, the proportion of people who reported dreaming in color was 29%.
