Answer to Problem 5P
Explanation of Solution
Given information:
The chirping rate of crickets of a certain species appears to be related to temperature shown in table.
Calculation:
It is observed from the scatter plot that all are linear,so linear model fits the data, by ising graphing calculator regression line will be,
Where
Now the plot for regression line is as follows,
Hence, the graph is plotted and regression line is
c.
Use the linear model in part (b) to estimate the chirping rate at
c.
