The life expectancy of a particular brand of tire is normally distributed with a mean of 40,000 and a standard deviation of 5,000 miles. what is the probability that a randomly selected set of tires will have a life of 36,000 to 46,000 miles? round your answer to 4 decimal places.

 0.6731

Step-by-step explanation:

Given : Mean :

Standard deviation :

The formula to calculate the z-score :-

For x=36,000

For x=46,000

The P-value :

Hence, the probability that a randomly selected set of tires will have a life of 36,000 to 46,000 miles =0.6731

answer: 20

step-by-step explanation: subtract the minimum date value from the maximum data value to find the date range. in this casem the date range is 42 - 22 = 20
