Expert Solution
Step 1

Given information:

The regression equation is mort=7.5264022+0.2250883 teen.

Parameter Estimates
Term Estimate Std. Error t Ratio Prob>|t| Lower 95% Upper 95%
Intercept 7.5264022 0.649296 11.59 <0.0001* 6.2194381 8.8333664
teen 0.2250883 0.050516 4.46 <0.0001* 0.1234047 0.3267719

The estimated value of the slope, b1 is 0.2250883.
