3. A consumer testing agency wants to evaluate the claim made by a manufacturer of discount tires. The manufacturer claims that their tires can be driven for at least 35,000 miles before wearing out. To determine the average number of miles that can be obtained from the manufacturer's tires, the agency randomly selects 60 tires from the manufacturer's warehouse and places the tires on 15 cars driven by test drivers on a 2-mile oval track. The number of miles driven (in thousands of miles) until the tires are determined to be worn out is given in the following table. Assume that the number of miles driven is normally distributed. 1 2 3 4 5 | 6 7 8 | 9 10 11 | 12 13 14| 15 n y Miles 25 27 35 42 28 37 40 31 29 33 | 30 26 31 28 30 15 31.47 5.04 Car S driven Based on the p-value, is there significant evidence that the manufacturer's claim is false. Use a = 0.01.

3. A consumer testing agency wants to evaluate the claim made by a manufacturer of discount
tires. The manufacturer claims that their tires can be driven for at least 35,000 miles before
wearing out. To determine the average number of miles that can be obtained from the
manufacturer's tires, the agency randomly selects 60 tires from the manufacturer's
warehouse and places the tires on 15 cars driven by test drivers on a 2-mile oval track. The
number of miles driven (in thousands of miles) until the tires are determined to be worn out
is given in the following table. Assume that the number of miles driven is normally
distributed.

The highway department wants to estimate the proportion of vehicles on a Toll road at KM 25 between midnight and 5:00 A.M. The department head wanted to see how many 18-wheel tractor trailers passed along the road. These estimates will be used to determine road improvement and construction considerations and in road patrol planning. The department head asked researchers to calculate the estimated vehicles at different locations on the inter-island road over the past 7 days. Of the 3,481 vehicles counted, 927 were 18 wheelers. However, out of a total of 927, there were 74 who had accidents, so the sample was calculated based on the results of reducing the number of accidents. Determine the point estimate for the proportion of vehicles traveling on KM 25 during this time period which are 18 wheelers! (Assume the confidence level is 99%). What is the benefit of estimating the estimated value in this case (analyze the answers you have obtained)?
