Suppose that the lifetimes of tires of a certain brand are normally distributed with a mean of 74000 miles and a standard deviat

spayn [35]

The standard deviation will be 6816.9645.

<h3>How to compute the standard deviation?</h3>

From the information given, the mean is 74000 and X is given as 60000.

P[(Z < (-60000 - 74000)/SD] = 0.02

Note that 0.02 will be -2.0537 under the normal distribution table.

-14000/SD = -2.0537

SD = -14000/-2.0537

SD = 6816.9645
