Two basketball players on a school team are working hard on
consistency of their performance. In particular, they are hoping to
bring down the variance of their scores. The coach believes that
the players are not equally consistent in their games. Over a
10-game period, the scores of these two players are shown below.
Assume that the two samples are drawn independently from normally
distributed populations. (You may find it useful to
reference the appropriate table: chi-square table or F...

The heights and weights of a random sample of male Senior HS
basketball players are given in the table. Is there enough evidence
that the heights and weights have a linear relationship?
height/weight: (76,246), (72,207), (75,220), (74,200), (72,170),
(71,175), (68,150), (74,210), (74,245), (72,200)

The population standard deviation for the height of college
basketball players is 2.9 inches. If we want to estimate a 99%
confidence interval for the population mean height of these players
with a 0.45 margin of error, how many randomly selected players
must be surveyed? (Round up your answer to nearest whole number, do
not include any decimals) Answer:
