A certain brand of automobile tire has a mean life span of 32,000 miles and a standard deviation of 2,450 miles. (Assume the life spans of the tires have a bell-shaped distribution.) (a) The life spans of three randomly selected tires are 34,000 miles, 37,000 miles, and 31,000 miles. Find the z-score that corresponds to each life span.

a)

The z-score corresponds to 34000 is 0.816

The z-score corresponds to 37000 is 2.041

The z-score corresponds to 31000 is -0.408

Step-by-step explanation:

The z-score corresponds to 34000

Let x=34000

z-score=(x-mean)/standard deviation

z-score=34000-32000/2450=0.816

The z-score corresponds to 34000 is 0.816

The z-score corresponds to 37000

Let x=37000

z-score=(x-mean)/standard deviation

z-score=37000-32000/2450=2.041

The z-score corresponds to 37000 is 2.041

The z-score corresponds to 31000

Let x=31000

z-score=(x-mean)/standard deviation

z-score=31000-32000/2450=-0.408

The z-score corresponds to 31000 is -0.408

answer: 193

explanation:

200-7 = 193

you forgot the options, but i found them anyways, the correct answer is "john wilson believes that words and actions based on the intellect are superior to those based on emotions".

john wilson is depicted as an extremely intelligent man. the point of the excerpt is to make a sort of distinction between emotional and rational intelligence. he happens to have both attributes, but he clearly favors his intellectual gifts. at the same time, because of his religious background, he's a little bit conflicted with this and it makes him ashamed.

hope this !
