Question

A certain brand of automobile tire has a mean life span of

32,000

miles and a standard deviation of

2,050

miles. (Assume the life spans of the tires have a bell-shaped distribution.)

(a) The life spans of three randomly selected tires are

35,000

miles,

36,000

miles, and

31,000

miles. Find the z-score that corresponds to each life span.

For the life span of

35,000

miles, z-score is

1.461.46.

(Round to the nearest hundredth as needed.)

For the life span of

36,000

miles, z-score is

1.951.95.

(Round to the nearest hundredth as needed.)

For the life span of

31,000

miles, z-score is

negative 0.49

I DONT KNOW HOW TO FIGURE OUT THE B SECTION BELOW

(b) The life spans of three randomly selected tires are

27,900

miles,

36,100

miles, and

32,000

miles. Using the empirical rule, find the percentile that corresponds to each life span.

The life span

27,900

miles corresponds to the

nothingth

percentile.

The life span

36,100

miles corresponds to the

nothingth

percentile.

The life span

32,000

miles corresponds to the

nothingth

percentile.

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 + ...
