Data collected over a long period of time show that the length of time x to complete a particular college entrance test is normally distributed with an average of 125 minutes and a standard deviation of 18 minutes. Ordinarily entrance tests have a time limit. What maximum time limit should be set for this entrance test if it is desired to have no more than 8% of test takers fail to finish the test during that time limit? Round your answer to the nearest minute. Don't forget that we round all z values to two decimal places.

Less than 8% of test takers will take longer than 150 minutes to finish the test.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 125 minutes

Standard Deviation, σ = 18 minutes

We are given that the distribution of length of time is a bell shaped distribution that is a normal distribution.

Formula:

We have to find the value of x such that the probability is 0.92

Calculation the value from standard normal z table, we have,  

Thus, less than 8% of test takers will take longer than 150 minutes to finish the test.

answ9x x 3=

step-by-step explanation:

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
