Expert Solution

Step 1

(a)

Obtain the value of b(slope)

The value of slope is obtained below as follows:

The value of x is obtained below:

From the information, given that

Thus, the value of x is 5.3

Obtain the value of y.

The value of y is obtained below:

The required value is,

Thus, the value of y is 5.4

Thus, the value of b is 0.6953.

Obtain the value of a

The value of a is obtained below:

The formula to obtain a is,

Thus, the value of a is 1.7148.

Thus, the required regression equation is,
