A manufacturer of boiler drums wants to use regression to predict the number of man-hours needed to erect drums in the future. The manufacturer collected a random sample of 35 boilers and measured the following two variables:

MANHRS:y = Number of man-hours required to erect the drum
PRESSURE:x1= Boiler design pressure (pounds per square inch, i.e., psi)

The simple linear model E(y) = β0 + β1x was fit to the data. A printout for the analysis appears below:

UNWEIGHTED LEAST SQUARES LINEAR REGRESSION OF MANHRS







Fill in the blank. At α =.01, there is ____________ between man-hours and pressure.
◦ sufficient evidence of a negative linear relationship
◦ sufficient evidence of a positive linear relationship
◦ sufficient evidence of a linear relationship
◦ insufficient evidence of a positive linear relationship
