Here is the table

PPG season PPG
1984-85 33.4
1985-86 27.2
1986-87 29.4
1987-88 26.9
1988-89 20.4
1989-90 23.7
1990-91 30.1
1991-92 32.8
1992-93 27.1
1994-95 24.9
1995-96 33.2
1996-97 26.8
1997-98 22.7
2001-02 37.9
2002-03 34.4

Here sample mean = = =  430.9/15 = 28.7267

Variance of the average points per game made per season by the basketball player=

s2 = 1/(n-1) [

= 23.9078

stnaddrd deviation of the average points per game = s =4.89 or 4.9 points

sample standard deviation of the average points per game made per season by the basketball player = 4.9 points

A baseball coach reviews the number of runs hit per game for the past several seasons. Since the team plays so many games, he selects a random sample of 10 games and records the number of runs scored in each game. The average number of runs scored is 8 with a standard deviation of 2.4 runs. Compute the margin of error given a confidence level of 99%.
