Question

Suppose that the average weight of students in a statistics class is 75.5 kilograms with a standard deviation of 10.3 kilograms.
A. 45% of the student weights are above ____ kilograms?

Z=.3264=x-75.5/10.3 Now what?

Answer 1

55% are below x

z = .1 ---> F(z) about .55

.1 = (x - 75.5)/10.3

x - 75.5 = 1.03

x = 76.5
