Question

The data show the bug chirps per minute at different temperatures. Find the regression​ equation, letting the first variable be the independent​ (x) variable. Find the best predicted temperature for a time when a bug is chirping at the rate of 3000 chirps per minute. Use a significance level of 0.05. What is wrong with this predicted​ value?

Chirps in 1 min   Temperature (°F)
1109   85.9
772   71.2
1228   86.7
1146   87.7
998   82
1195   91.9

Answer 1

regression​ equation is y = 40.856 + 0.04⋅x

Given x = 3000 then

y = 40.856 + 0.04 ( 3000 )

y = 160.856

It is not meaningful because the value x = 3000 is not in the orginal data
