Question:

Refer to Exercise 33. Here is a graph of period2 versus length, along with output from a linear regression analysis using these variables.

5 4 2 20 30 40 50 60 70 80 90 100 110 Length (cm) Period? 3.


a. Give the equation of the least-squares regression line. Define any variables you use.

b. Use the model from part (a) to predict the period of a pendulum with length 80 centimeters.


Exercise 33.

Mrs. Hanrahan’s precalculus class collected data on the length (in centimeters) of a pendulum and the time (in seconds) the pendulum took to complete one back-andforth swing (called its period). The theoretical relationship between a pendulum’s length and its period is


where g is a constant representing the acceleration due to gravity (in this case, g = 980 cm/s2). Here is a graph of period versus length, along with output from a linear regression analysis using these variables.
