A company makes windows for use in homes and commercial buildings. The standards for glass thickness call for the glass to average 0.425 inch with a standard deviation equal to 0.050 inch. Suppose a random sample of n =48 windows yields a sample mean of 0.423 inch. Complete parts a and b below. a. What is the probability of)? 2 0423 if the windows meet the standards? P (i 2 0.423) = (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 Y meeting the standards. because a sample of 43 windows with a sample mean of 0.428 inch Y if the population actually had a mean of0.425 inch and a standard deviation of 0.050 inch
