Problem: The heights of a group of boys are normally distributed with a mean of 54 inches and standard deviation of 2.5 inches. 4. If all possible samples of size 25 are drawn from this population, what percentage of them would have means between 53 inches and 55 inches? 5. If a random sample of size 81 is drawn from this population, what is the probability that the mean of this sample is larger than 53.5 inches?

8. An HP laser printer is advertised to print text documents at a speed of 18 ppm (pages per minute). The manufacturer tells you that the printing speed is actually a Normal random variable with a mean of 17.57 ppm and a standard deviation of 3 ppm. A Brother brand printer can print an average of 17.21 ppm and a standard deviation of 4 pages and its printer speed is also normally distributed. You select 10 of each printer at random. What is the probability that mean Brother print speed is at least 2 pages faster than the mean HP print speed?
