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.
