**Answer:**

A) **The linearity conditions are satisfied.**

b) **Yes there is positive linear association because attendance per game increases then pitcher age also increases.**

**c) The pitcher age increases by 1 year the average attendance tend to increase by about 5511 fans.**

**Step-by-step explanation:**

We get( check the first attached for the excel computation)

Conditions.

A) **The linearity conditions are satisfied.**

b) **Yes there is positive linear association because attendance per game increases then pitcher age also increases.**

c) y : Dependent variable = attendance per game

x : independent variable = pitchers age

We can solve this question using excel.

First enter data into excel.

Click on Data -------> Data Analysis --------> Regression ------->

Input

Input Y Range : select y values

Input X Range :select values of x.

Output Range : select any empty cell

---------> ok

We get ( check the first attached for the excel computation)

The regression equation is

Attendance = - 124506 +5511 x age

Test statistic for slope is 6.797

P-value for test statistic is 0.0000191

**The pitcher age increases by 1 year the average attendance tend to increase by about 5511 fans.**
