Math Problem Statement

Data on tuition and mid-career salary are collected from a number of universities and colleges. The result of the data collection is the linear regression model

where annual tuition and average mid-career salary of graduates, both in thousands of dollars.

Which quantity is the independent variable? average mid-career salary of graduates annual tuition

According to this model, what is the average salary for a graduate of a college or university where the annual tuition is $30,000? $ What is the slope of this regression model?

Solution

To help answer your questions, I need the actual linear regression model. This model typically has the form:

y=mx+by = mx + b

where:

  • yy represents the dependent variable (in this case, the average mid-career salary),
  • xx represents the independent variable (in this case, the annual tuition),
  • mm is the slope of the regression line, and
  • bb is the y-intercept.

Please provide the model, or if you have any specific data or coefficients that you can share, I can help you calculate the answers based on that.
