A simple regression analysis is performed to relate maintenance expense (Y, dollars per month}to usage (X, hours per week}. A random sample of 82 observations showed an Fstatistic of 10 in theANOVAtable, and the scatter plot suggested that maintenance expense increases as usage increases. The sample variance of Y is 100. Question 19. If the sample variance of X is 1X36, the slope of the simple regression line is 020 015 01 010 05
