The manager of a local shopping mall uses simple linear regression to develop an equation that predicts the number of daily shoplifting incidents at the mall's stores based on the number of security guards employed.The manager uses the following data: The slope of the regression line is b = -1.2; the intercept of the regression line is a = 14.5.Produce the 95% confidence interval for the estimate of the population slope, β, and use it to complete the following sentence:
With 95% confidence, the slope of the population regression line is between ______ and ______.
A)-3.8, 1.3
B)-2.9, 31.9
C)-2.06, 3.59
D)-1.2, 14.5
