b. Years of professional experience has a p-value of .80 , hence is insignificant
Q2:
c. Age &; years of experience. They have a correlation of .73 between them, which is a very high correlation
Q3:
I conducted linear regression model without a. Number of minor home runs and found that the p-values of remaining 2 variables
is more than .05, hence, we can't do without this variable.
a. Number of minor home runs is CORRECT answer for this question
