Doctors are interested in the relationship between the dosage of a medicine and the ime required for a patient's recovery. Table 2 shows, for a sample of 10 patients, dosage levels (in grams) and recovery times (in hours). These patients have similar characteristics except for medicine dosages. Table 2: Dosage Level and Recovery Time Patient Dosage Level Recovery Time 1.2 25 2 1.3 28 1.0 40 4 1.4 38 5 1.5 10 6. 1.8 9 7 1.2 27 8 1.3 30 9. 1.4 16 10 1.3 18 a. Estimate the linear regression of recovery time on dosage level. b. Compute R2 and interpret it. c. Perform an F test of goodness of fit at the 5% significance level.
