Regression: icu versus age Simple Analysis of Variance Source DF Adj SS Adj MS F-Value P-Value Regression 565.00 1 261.837 26

Now we will calculate the 95% confidence interval for the slope of the population regression line using the following steps:The first photo is the data I had collected in Minitab.I am confused on what the b1= to then get the degree of freedom. I need this information to answer question 16 to plug in the right information in minitab to get t*multiplier. Overall need help with getting the answer to #16 so then I can continue the rest of the problems. Thanks! (also for 17 what is S.E.)

Answer #1

16). t*= 1.972017 [by using the steps you have mentioned.please perform this in minitab express ,in minitab you will not get the options.]

17).the margin of error = ( t* * se(b1)) = (1.972017 *0.680753) = 1.342

*** If you have any doubt regarding the problem please write it in the comment section.if you are satisfied please give me a LIKE if possible...
