Given the following data:

Number of patients = 3,293

Number of patients who had a positive test result and had the disease = 2,184

Number of patients who had a negative test, and did NOT have the disease = 997

Number of patients who HAD a positive test result, but did NOT have the disease = 55

Number of patients who had a negative test result, but who HAD the disease = 57

a. Create a complete and fully labelled 2x2 table (10)

b. Calculate the positive predictive value (5)

c. Calculate the negative predictive value (5)

d. Calculate the likelihood ratio for a positive test result (5)

e. Calculate the likelihood ratio for a negative test result (5)

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...
