Medical researchers often use linear regression to understand therelationship between new drug dosage and blood pressure. A labdeveloped two new drugs, 15 sample of each were administered.Test subjects' blood pressure and associated dosage data is listedbelow. Determine how newly developed drugs affect the bloodpressure. Describing how well the model fits the data.Drug "A"Dosage:[50mg 100mg 150mg 200mg 250mg 300mg 350mg400mg 450mg 500mg 550mg 600mg 650mg 700mg750mg]Blood Pressure:[120mmHg 121mmHg 123mmHg 124mmHg 125mmHg124mmHg 126mmHg 125mmHg126mmHg 128mmHg 131mmHg 130mmHg 132mmHg132mmHg 134mmHg]Drug "B"Dosage:[50mg 100mg 150mg 200mg 250mg 300mg 350mg400mg 450mg 500mg 550mg 600mg 650mg 700mg750mg]Blood Pressure:[119mmHg 120mmHg 120mmHg 121mmHg 122mmHg120mmHg 119mmHg 120mmHg119mmHg 123mmHg 120mmHg 121mmHg 122mmHg122mmHg 120mmHg]Write your own function to solve both problems.

How do you figure this out using conjoint analysis in a linear regression? Determine how various attributes impact the purchase of a car. There are four attributes, each with three levels: Brand: Ford = 1, Chrysler = 2, GM = 3 MPG: 15 MPG = 1, 20 MPG = 2, 25 MPG = 3 Horsepower (HP): 100 HP = 1, 150 HP = 2, 200 HP = 3 Price: $18,000 = 1, $21,000 = 2, $24,000 = 3 The nine product profiles ranked in the data file were evaluated by a consumer. (a) For this market segment, rank the product attributes from most important to least important. Below is the data provided.

$339,380 $41,768 A national homebuilder builds single-family homes and condominium-style townhouses. The accompanying dataset provides information on the selling price, lot cost, and type of home for closings during one month. Complete parts a through c. E Click the icon to view the house sales data a. Develop a multiple regression model for sales price as a function of lot cost and type of home without any interaction term. Create a dummy variable named "Townhouse", where it is equal to 1 when Type = "Townhouse" and 0 otherwise. Determine the coefficients of the regression equation. Sales Price = 108726 + (3.68 ) • Lot Cost + ( - 75063 )• Townhouse (Round the constant and coefficient of Townhouse to the nearest integer as needed. Round all other values to two decimal places as needed.) b. Determine if an interaction exists between lot cost and type of home and find the best model. Use a = 0.1 as the level of significance. First determine whether an interaction exists. Select the…
