Question

An over-the-counter drug manufacturer wants to examine the effectiveness of a new drug in curing an iness most commonly found in older patients Thirteen patients are given the new drug and 13 patients are given the old drug. To avoid bias in the experiment, they are not told which drug is given to them. To check how the effectiveness depends on the age of patients, the following data have been collected Patient Age 19 23 67 56 45 37 27 47 29 59 51 63 28 New Drug: Effectiveness 28 25 71 62 50 46 34 59 36 71 62 71 35 Patient Age 21 28 33 33 38 43 48 53 53 58 63 67 52 old Drugi Effectiveness 56 55 61 54 58 65 64 61 69 71 66 70 60 The variables are Effectiveness the response variable measured on a scale from 0 to 100, Age - the age of a patient in years) Drug a binary variable with 1 for the new drug and for the old drug The regression model, EffectivenessPo + Age + P2Drug + B3 Age Drug, is estimated and the following results are obtained Intercept Age Coefficients Standard Errort-stat 47.04 3. 1479 14.9423 0.34 0.0665 5.0610 -40.86 4.0798 -10.016 0.70 0.0879 7.9385 P-value 5.31E-13 4.55E-05 1.178-09 6.71E-08 Drug Age Drug Which of the following is the estimated regression model?
