The heights of 2000 students are normally distributed with a mean of 166.5 centimeters and a standard deviation of 7.7 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 148.0 centimeters? (b) between 163.5 and 178.0 centimeters inclusive? (c) equal to 167.0 centimeters? (d) greater than or equal to 186.0 centimeters? Click here to view page 1 of the standard normal distribution table.
