The Tire Rack, America's leading online distributor of tires and wheels, conducts extensive testing to provide customers with products that are right for their vehicle. The following data show survey ratings (1 to 10, with 10 being the highest) for 18 summer tires. Develop an estimated regression equation that can be used to predict the Buy Again rating given based on the Steering and Tread wear rating. How many percent of the variation in the Buy Again variable could be predicted by Steering and Thread wear rating?
Note: put answers into decimal form, if your answer is 90.8765%, enter in 0.908765.
Solutions
Expert Solution
X1 =Steering
X2 =Thread wear
Y =Buy Again
So, the regression equation is:
=0.68987X1
+ 0.91133X2 - 5.38767
Coefficient of determination, R2 =0.931762.
So, 93.1762 percent of the variation in the Buy Again variable could be predicted by Steering and Thread wear rating.

A tire company has developed a new type of steel-belted radial
tire. Extensive testing indicates the population of mileages
obtained by all tires of this new type is normally distributed with
a mean of 39,531 miles and a standard deviation of 4,075 miles. The
company wishes to offer a guarantee providing a discount on a new
set of tires if the original tires purchased do not exceed the
mileage stated in the guarantee. What should the guaranteed mileage
be if...

After extensive research and development, Goodweek Tires, Inc.,
has recently developed a new tire, the SuperTread, and must decide
whether to make the investment necessary to produce and market it.
The tire would be ideal for drivers doing a large amount of wet
weather and off-road driving in addition to normal freeway usage.
The research and development costs so far have totaled about $10
million. The SuperTread would be put on the market beginning this
year, and Goodweek expects it...

.Tire manufacturer is interested in testing the fuel economy for
two different tread patterns. Tires of each tread type were driven
for 1000 miles on each of 9 different cars. The mileages, in miles
per gallon, were as follows. Test whether the mean mileage is the
same for both types of tread. (ANOVA test)

A bicycle manufacturer buys 5000 tires a year from a distributor. It cost 6 to store one bicycle tire for a year. To re-order, there is a fixed cost of $24 per shipment plus $11 for each tire. How many times per year should the manufacturer order bicycle tires and in what lot size, to minimize inventory cost?
