The heights of 1500 students are normally distributed with a mean of 166.5 centimeters and a standard deviation of 7.9 centimeters. Assuming that the heights are recorded to the nearest half-centimeter, how many of these students would be expected to have heights:(a) less than 151.0 centimeters?(b) between 161.5 and 175.0 centimeters inclusive?(c) equal to 168.0 centimeters?(d) greater than or equal to 181.0 centimeters?[Click here to view page 1 of the standard normal distribution table.](#)[Click here to view page 2 of the standard normal distribution table.](#) Given a normal distribution with μ = 35 and σ = 7, find(a) the normal curve area to the right of x = 20;(b) the normal curve area to the left of x = 26;(c) the normal curve area between x = 38 and x = 48;(d) the value of x that has 85% of the normal curve area to the left; and(e) the two values of x that contain the middle 75% of the normal curve area.[Click here to view page 1 of the standard normal distribution table.](#)[Click here to view page 2 of the standard normal distribution table.](#)

For a data set of the pulse rates for a sample of adult females, the lowest pulse rate is 33 beats per minute, the mean of the listed pulse rates is x =74.0 beats per minute, and their standard deviation iss = 13.2 beats per minute. a. What is the difference between the pulse rate of 33 beats per minute and the mean pulse rate of the females? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the pulse rate of 33 beats per minutes to a z score. d. If we consider pulse rates that convert to z scores between -2 and 2 to be neither significantly low nor significantly high, is the pulse rate of 33 beats per minute significant? a. The difference is beats per minute. (Type an integer or a decimal. Do not round.) b. The difference is standard deviations. (Round to two decimal as needed.) c. The z score is z= (Round to two decimal places as needed.) d. The lowest pulse rate is
