Crickets and Temperature Biologists have observed that thechirping rate of crickets of a certain species is related to temperature, and the relationship appears to be very nearlylinear. A cricket produces 120 chirps per minute at 70F and168 chirps per minute at 80F.(a) Find the linear equation that relates the temperature t andthe number of chirps per minute n.(b) If the crickets are chirping at 150 chirps per minute,estimate the temperature.
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 predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.

chirping rate of crickets of a certain species is related to temperature, and the relationship appears to be very nearly
linear. A cricket produces 120 chirps per minute at 70F and
168 chirps per minute at 80F.
(a) Find the linear equation that relates the temperature t and
the number of chirps per minute n.
(b) If the crickets are chirping at 150 chirps per minute,
estimate the temperature.
