Discussion:
Outside Magazine tested 10 different models of day hikers and backpacking boots. The following data show the upper support and price for each model tested. Upper support was measured using a rating from 1 to 5, with a rating of 1 denoting average upper support and a rating of 5 denoting excellent upper support.
Manufacturer and Model Support ; Price
Salomon Super Raid 2 ; 120
Merrell Chameleon Prime 3 ; 125
Teva Challenger 3 ; 130
Vasque Fusion GTX 3 ; 135
Boreal Maigmo 3 ; 150
L.L. Bean GTX Super Guide 5 ; 189
Lowa Kibo 5 ; 190
Asolo AFX 520 GTX 4 ; 195
Raichle Mt. Trail GTX 4 ; 200
Scarpa Delta SL M3 5 ; 220
a. Use these data to develop an estimated regression equation to estimate the process of a day hiker and backpacking boot given the upper support training.
b. At the .05 level of significance, determine whether upper support and price are related.
c. Would you feel comfortable using the estimated regression equation developed in part (a) to estimate the price for a day hiker or backpacking boot given the upper support rating?
d. Estimate the price for a day hiker with an upper support rating of 4.
