Explanation / Answer

Question 8

Part a

The coefficient b1 is given as below:

b1 = 1.59

(by using regression output)

Part b

The coefficient b0 is given as below:

b0 = 5.06

(by using regression output)

Part c

We are given

X = 25

Regression equation is given as below:

Ridership = Y-hat = b0 + b1*X

Ridership = 5.06 + 1.59*X

Ridership = 5.06 + 1.59* 25

Ridership = 44.81

Answer = 44.81

Part d

We are given

X = 5

Ridership = Y-hat = b0 + b1*X

Ridership = 5.06 + 1.59*X

Ridership = 5.06 + 1.59* 5

Ridership = 13.01

Answer = 13.01

Question 9

Part a

b1 = 1.59

Part b

b0 = 5.06

Part c

Here, X = 17

Ridership = Y-hat = b0 + b1*X

Ridership = 5.06 + 1.59*17

Ridership =32.09

Part d

Here, X = 19

Ridership = Y-hat = b0 + b1*X

Ridership = 5.06 + 1.59*19

Ridership =35.27
