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?

What is the regression equation?
What is the best predicted temperature for a time when a bug is chirping at the rate of 3000 chirps per minute?
What is wrong with this predicted value? Choose the correct answer below.
A. It is unrealistically high. The value 3000 is far outside of the range of observed values.
B. The first variable should have been the dependent variable.
C. It is only an approximation. An unrounded value would be considered accurate.
D. Nothing is wrong with this value. It can be treated as an accurate prediction.

- Shelia's doctor is concerned that she may suffer from gestational diabetes (high blood glucose levels during pregnancy). There is variation both in the actual glucose level and in the blood test that measures the level. A patient is classified as having gestational diabetes if the glucose level is above 140 milligrams per deciliter (mg/dl) one hour after a sugary drink. Shelia's measured glucose level one hour after the sugary drink varies according to the Normal distribution with µ = 124 mg/dl and σ = 13 mg/dl.
