Textbook Problem

A local gym charges a $25 monthly membership fee plus $2 per hour for aerobics classes. What is the linear equation that describes the relationship between the total monthly cost (*Y*) and the number of class hours each month (*X*)?

Expert Solution

To determine

The linear equation between local gym changes and aerobics classes total monthly cost *(Y)* and the number of class hours each month *(X)*.

**Given info:**

A local gym, charges a $25 monthly membership fee plus $2 per hour for aerobics classes.

**Calculation:**

*Simple linear regression:*

The Simple linear regression is a statistical method that is used to the study relationships between two continuous (quantitative) variables: One variable x, is denoted as the predictor or explanatory or independent variable and the variable y is denoted as the dependent variable and response variable.

Linear equation form is

Where *b* is constant and the form *aX* varies with the value of X
