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. To answer the question input only the actual whole number. Do not include units. Do not give your answer in sentence form -- just include the numerical answer.
