Question

1. You are examining the relationships between employee sales and characteristics of employees who work in a call center. You see that years of previous non-manager work experience has a correlation coefficient of r.35 while years of previous managerial experience has a correlation coefficient of r-42. As compared to previous manager work experience, previous non-manager work experience is more highly correlated with employee sales. True False 2. The correlation between number of Ads run and sales is .6 and it is statistically significant at the .01 level. That means that a linear relationship is necessarily the best way to describe the relationship between the two variables. True False 3. In a simple linear regression, an analyst reports that the p value of the slope estimate is.07 while the p value of the F statistic is.02. This is a plausible answer. True False

Answer 1

(1) TRUE because sales under non manager , the correlation coefficient is 0.35 whereas under manager correlation is -0.42.

(2) TRUE because the correlation is 0.6 which is very highly positive so we can conclude that there is some linear relation between two variables.

(3) TRUE . This is plausible , if p value for slope is greater than the F statistics we accept the null hypothesis otherwise reject the null hypothesis.
