Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as p…

Critical Thinking Exercises

Make Sense? Read this expert from an advertisement for bikes with aerodynamic coverings.

Our high-performance bicycles have the aerodynamic design of custom racing bikes, but are practical for everyday riding. The aerodynamic covering will increase your average speed by 10 miles per hour. Cyclists using our bicycles, versus bikes without aerodynamic covering, reduce time on a 75-mile test run by 2 hours.

Chapter 6.7, Problem 70E, Critical Thinking Exercises Make Sense? Read this expert from an advertisement for bikes with

Now you are interested in finding the average rate of the bikes with the aerodynamic coverings on the 75-mile test run. With this goal in mind, determine whether each statement in Exercises 67–70 makes sense or does not make sense, and explain your reasoning.

My professor verified that 15 is the correct value for x in the equation modeling the conditions, so I used my table from Exercise 67 and conclude that the average rate of the covered bikes on the 75-mile test run was 15 miles per hour.
