Question

During the 2009-2010 basketball season, the number of points scored in each game by the Boston Celtics was approximately normally distributed with a mean of 99.2 points and a standard deviation of 10.5 points.

1)What is the 33rd percentile of points scored by the Celtics?

2)The mean number of points scored by the Los Angeles Lakers was 101.7. In what proportion of their game did the Celtics score more than the Lakers' mean score?

Answer 1

The Table for Standard Normal Distribution is organized as a cummulative 'area' from the LEFT corresponding to the STANDARDIZED VARIABLE z. The Standard Normal Distribution is also symmetric (called a 'Bell Curve') which means its an interpretive procedure to Look-Up the 'area' from the Table.

For STANDARDIZED VARIABLE z = -0.44 the Table left column shows two (2) significant digits and one (1) additional significant digit in the top row corresponding to a LEFT 'area' = 0.33.


33% Score = 99.2 - 0.44 * 10.5
