4) At a fitness club, an analysis is done of the time (hours/week) a member spends on fitness classes compared to the time the member spends on equipment. A sample of 7 members was used and the resulting Minitab shown below. Assume both x and y form normal distributions. Partial output from XLSTAT is below. 1. The slope of the regression line is a. 0.797 b. 3.78 c. 0.1944 d. -4.098 2. The correlation coefficient is a. 0.878 b. 0.771 c. 0.851 d. none of the above* A hypothesis test is done to determine whether the correlation coefficient is significantly different from zero. Answer the following 4 questions about this Model parameters: hypothesis test. 3. The alternate hypothesis is: a. H1:=0 b. H1:=0 c. H1:=0 d. H1:=0 4. The test statistic is a. -2.382 b. -1.856 c. 4.098 d. none of the above 5. The degrees of freedom are: a. 7 b. 6 c. 5 d. 4 6. At the 1% significance level it can be concluded. a. The correlation coefficient is negative. b. The correlation coefficient is zero. c. The correlation coefficient is positive. d. None of the above*
