A company makes windows for use in homes and commercial buildings. The standards for glass thickness call for the glass to average 0.375 inch with a standard deviation equal to 0.055 inch. Suppose a random sample of n = 40 windows yields a sample mean of 0.403 inch. Complete parts a and b below a. What is the probability of x 2 0.403 if the windows meet the standards? P (x=0 403) = (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 40 windows with a sample mean of 0.403 inch if the population actually had a mean of 0.375 inch and a standard deviation of 0 055 inch
