Answer: There is a strong positive correlation between number of games won by a minor league baseball team and the average attendance at their home games is analyzed.

Step-by-step explanation:

The Pearson's coefficient 'r' gives the correlation between the predicted values and the observed values.

It tells the direction and the strength of the relation. When r is negative it means there is a negative relationship between the variables. When r is positive it means there is a positive relationship between the variables. When |r|=1, strong correlation, When r=0, there is no correlation. If 0.70<|r|<1, there is a strong correlation. If 0.50<|r|<0.70, there is a moderate correlation. If 0.30<|r|<0.50, there is a low correlation.

Given : A regression to predict the average attendance from the number of games won has an r = 0.73.

Since r=0.73 is positive and 0.70 <0.73 <1, it means there is a strong positive correlation between number of games won by a minor league baseball team and the average attendance at their home games is analyzed.
