A company makes windows for use in homes and commercial buildings. The standards for glass thickness call for the glass to average 0.350 inch with a standard deviation equal to 0.045 inch. Suppose a random sample of n = 44 windows yields a sample mean of 0.369 inch. Complete parts a and b below. a. What is the probability of x 2 0.369 if the windows meet the standards? P (x20.369) = (Round to four decimal places as needed.) b. Based on your answer to part a, what would you conclude about the population of windows? Is it meeting the standards? (A result is unusual if it has a probability less than 0.05.) The population of windows meeting the standards, because a sample of 44 windows with a sample mean of 0.369 inch if the population actually had a mean of 0.350 inch and a standard deviation of 0.045 inch. would be unusual would not be unusual
