# Case memo - Statistics Project Example

## Extract of sample Case memo

This data represent 21 New Jersey counties.
This report will examine correctness of the charge that New Jersey banks have been withdrawing from urban areas with a high percentage of minorities.

The importance of this study is to test whether banks serve their own communities.
A scatterplot is created taking “x” as the percentage of the population within each county that is minority and “y” as people in each county per branch bank within the county.

This is a strong effect. However, the other 47.35% of the variation in the number of people in county per branch bank remains unexplained.
The slope coefficient of regression of 35.89 suggests that for every percent increase in minority population in the county, the number of people per bank branch increases by about 36 on average. The intercept coefficient of regression of 2082 suggests that for no minority population in the county, the number of people per bank branch will be about 2,082 on average.
The p-value for “x” variable the percentage of minority population in the county is 0.0002, which is less than 0.01. Therefore, the percentage of minority population in the county significantly predicts the number of people in county ...Show more
