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

30003000

chirps per minute. Use a significance level of 0.05. What is wrong with this predicted​ value?

Temperature ​(degrees°​F)	88.388.3	83.183.1	65.465.4	74.674.6	70.670.6	83.183.1

What is the regression​ equation?

ModifyingAbove y with caretyequals=nothingplus+nothingx

​(Round the​ x-coefficient to four decimal places as needed. Round the constant to two decimal places as​ needed.)

What is predicted y = round one decimal

What is wrong with the predicted value?

Answer 1

y = 31.98 + 0.0486 x

Given x = 3000 then

y = 31.98 + 0.0486 ( 3000 )

y = 177.8

It is not meaningful to have x = 3000 because it is not in the orginal data
