A researcher compares two compounds (1 and 2) used in the manufacture of car tires that are designed to reduce braking distances for SUVs equipped with the tires. The mean braking distance for SUVs equipped with tires made with compound 1 is 50 feet, with a population standard deviation of 12.4. The mean braking distance for SUVs equipped with tires made with compound 2 is 54 feet, with a population standard deviation of 13.0. Suppose that a sample of 71 braking tests are performed for each compound. Using these results, test the claim that the braking distance for SUVs equipped with tires using compound 1 is shorter than the braking distance when compound 2 is used.

A researcher compares two compounds (1 and 2) used in the manufacture of car tires that are designed
to reduce braking distances for SUVs equipped with the tires. The mean braking distance for SUVs
equipped with tires made with compound 1 is 50 feet, with a population standard deviation of 12.4.
The mean braking distance for SUVs equipped with tires made with compound 2 is 54 feet, with a
population standard deviation of 13.0. Suppose that a sample of 71 braking tests are performed for
each compound. Using these results, test the claim that the braking distance for SUVs equipped with
tires using compound 1 is shorter than the braking distance when compound 2 is used. Let μ₁ be the
true mean braking distance corresponding to compound 1 and µ₂ be the true mean braking distance
corresponding to compound 2. Use the 0.1 level of significance.
Step 3 of 5: Find the p-value associated with the test statistic. Round your answer to four decimal
places.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
