Question

with a height of 68 in, George was the shortest president of a particular club in the past century. the club presidents of the past century have a mean height of 75.1 in and a standard deviation of 2.6 in.

What is the positive difference between George height and the
mean?

b. How many standard deviations is that[the difference found in
part(a)]?

c. Convert George height to a z score.

d. If we consider “usual" heights to be those that convert to z
scores between minus−2 and 2, is Johnson’s height usual or
unusual?

Answer #1

b. To find the number of standard deviations, we can take the
difference from part a and divide by the standard deviation. In
this case, that would be 7.1/2.6= 2.73 . George's 2.73 standard
deviations below the mean.

c. Any z-score can be found with the following formula: z = (X -
M)/SD, where X is a person's score, M is the mean, and SD is the
standard deviation. In this case we have z = (68 - 75.1)/2.6=
-2.73

d. If we consider z-scores between - 2 and 2 to be usual, then
George's score would be unusual because he is outside of that
range.

The tallest living man at one time had a height of 241 cm. The
shortest living man at that time had a height of 126.5 cm. Heights
of men at that time had a mean of 170.29 cm and a standard
deviation of 6.72 cm. Which of these two men had the height that
was more extreme?
Since the z score for the tallest man is zequals
nothing and the z score for the shortest man is zequals

Heights are generally normally distributed. Men have a mean of
69.5 inches and standard deviation 2.4 inches. Women have a mean of
63.8 inches and standard deviation 2.6 inches. The US Air Force has
a height requirement for their pilots to be between 64 inches and
77 inches.
Make sure you are rounding z-scores properly to two
places.
Part A: Find the two z-scores for women who meet this height
requirement z = (smaller value) and z
= (larger value)
Part B:...
