The 2x2 contingency table is as follows :-

Had the disease Did not have the disease Total
Positive test result 2184 55 2239
Negative test result 57 997 1054
Total 2241 1052 3293

The PulseRates data set has pulse, height and weight for 90 patients who had an echocardiogram test in one of the clinic in Ottawa in the month of September. (a)[2] Fit a L-S regression line using height to predict the pulse rate (pulse rate is called the response variable). What is the equation of the L-S regression line? . Does it make sense to use this line? Why? (Check the correlation coefficient) (b)[2] Fit a L-S regression line using weight...
