Question

Find the expected value and standard deviation of heights for a basketball player on Team Z given the the following information. hint: find the probability (relative frequency) for each height first: Height (x in inches) # of Players 72 1 73 3 74 3 75 5 76 6 77 5 78 3 79 1 2. How would the expected value and standard deviation change if the height for every player was was actually 1 inch taller? Provide both an explanation and mathematical solution.

Answer #1

Data show that men between the ages of 20 and 29 in a general
population have a mean height of 69.3 inches, with a standard
deviation of 2.9 inches. A baseball analyst wonders whether the
standard deviation of heights of major-league baseball players is
less than 2.9 inches. The heights (in inches) of 20 randomly
selected players are shown in the table.
