Which description best fits the regression model for the data?
logistic equation of the form y = , with
a = 7.576, b = 0.001, and c = –1.107
a = 7.576, b = 0.001, and c = –1.107
logistic equation of the form y = , with
a = 0.001, b = –1.107, and c = 7.576
a = 0.001, b = –1.107, and c = 7.576
trigonometric equation of the form y = a sin(bx + c) + d, with a = 4.15, b = 0.34, c = 497.43, and d = 3.80
trigonometric equation of the form y = a sin(bx + c) + d, with a = –4.15, b = –0.34, c = –497.43, and d = 3.80
Expert Solution
Step 1
Given
The data of records the length, in inches, of a colored pencil over time
The length of the colored pencil will converge to zero as time increases, so cannot use a trigonometric regression.
Using a TI 84 calculator to see the best fit logistic regression equation we follow these steps
Press STAT and Click on EDIT
Enter the data in list 1 and list 2 as shown below
Press STAT and select the CALC and in CALC select option B as shown below
