An accountant knows from experience that the time it takes her to prepare a tax return is normally distributed with a mean of 1.6 hours and a standard deviation of 0.9 hours. She has 18 tax returns to prepare before April 15. What is the probability that the mean time for preparation of the random 18 returns will be less than 1.5 hours? Round your answer to 3 decimal places.

Accrotime is a manufacturer of watches. Accotime researchers have shown that watches hwe an average life of 28 months before certain electronic components deteriorate causing the watch to become unreliable. The standard deviation of watch lifetimes is 5 months and the distribution is noemal. If Accrotime guarantees a full refund of any defective watch for 1.5 years after the purchase, what percentage of total production will the company expect to replace? Write your answer as a percentage rounded to 1 decimal place. For the toolbar, Press ALT+F10 (PC) or ALT+FN+F10 OMCA) 0 WOAOS POWEASD BY TINY
