Using a Regression Analysis
QUESTION: Enter the midline temperature asY2.Use your TI calculator, to solve for the values of t for which the temperature is equal to the midline (there should be 2). Approximately when on the calendar does this occur?
Using Regression Analysis:
y=23.97sin(0.51x + 2.02)+51.67
Amplitude= 23.97
Period= 12.32
Midline= 51.67
F(3.5)= 46.1 (middle of March, the average high temp is 46.1 degrees)
Original Data:
Month123456789101112Average High Temperature282940546571767364514134
The max temperature is 76 degrees. It occurs in month 7, July.
The min temperature is 28 degrees. It occurs in month 1, January.
y=52 midline
A=24 amplitude
period=12 months
midline is at t=4, April month 4 is midline and rising
