Concept explainers
a.
To make: a scatter plot of given data.
a.
Answer to Problem 22E
The scatter plot of the data is show
Explanation of Solution
Given:
Biologist have observed that chirping rate of crickets rate appears to be related to temperature. The given table shows chirping rates for various temperatures:
Temperature | Chirping rate(chirps per minutes) |
Calculation:
The scatter plot of the data is shown below:
b.
To find: the graph and regression line.
b.
Answer to Problem 22E
Explanation of Solution
Biologist have observed that chirping rate of crickets rate appears to be related to temperature. The given table shows chirping rates for various temperatures:
Temperature | Chirping rate(chirps per minutes) |
Calculation:
According to the table, to make a linear regression line and obtained the equation:
Now, graph of the regression line is shown below
Hence, a linear regression line model is
c.
To estimate: the chirping rate by using a linear model in part (b).
c.
Answer to Problem 22E
Explanation of Solution
From part (b)
Chirping rate is
Calculation:
According to the table, to make a linear regression line and obtained the equation:
Now, plug the value of
Hence, the chirping rate of the linear model is
