The difference between simple and multiple linear regression is that A. Simple regression has only one dependent variable. B. Simple regression has multiple dependent variable. C. Multiple regression has multiple dependent variable. D.Simple regression has only one independent variable. QUESTION 22 The basic method used in regression analysis is called A. the linear squares method B. the maximum squares method C. the maximum regression method D. the ordinary least squares method A pack of gum at the grocery store is \( \$ 1.75 \). We collect data on the amount of money different customers spend on gum and the number of packs of gum they purchase and then estimale this relationship with a simple linear regression model. The standard error of the estimate will be zero. True False QUESTION 24 After estimating a simple linear regression model, scientists ty to test the significance of their results and find a p-value of \( 0.0567 \). This implies that the null hypothesis cannot be rejected for a significance level of \( 10 \% \). True False Which of the following is NOT true, when comparing two populations? A. The difference in means is normally distributed if the sample sizes are larger than 30 . 8. The difference in means is a random variable. C. The difference in means is normally distributed only if the two populations are normal. D. The sample mean difference is an unblased estimator of the population mean difference. ASHSU history professor wants to test his theory that the ditterence in salaries for business professors (group 1) and history professors (group 2) is larger han \( \$ 20,000 \) (business prolessors eam over 20,000 more than their history counterparts). To test his hypothesis, he randomly selects a sample of 52 business professors and finds their average salary to be \( \$ 94155 \). He also selects a random sample of 73 history professors and finds their average salary is \( \$ 67793 \). The sample standard deviations are equal to \( \$ 7000 \) for business professors, respectively \( \$ 6500 \) for history professors. He wants to perform this test using a significance level of \( 5 \% \). Compute the tesi slatistic needed for performing this test. Round your answer to 2 decimals, if needed.
