You run a regression analysis on a bivariate set of data (n=87n=87). You obtain the regression equationy=−3.815x+47.575y=-3.815x+47.575with a correlation coefficient of r=−0.349r=-0.349 (which is significant at α=0.01α=0.01). You want to predict what value (on average) for the explanatory variable will give you a value of 160 on the response variable.What is the predicted explanatory value?x = (Report answer accurate to one decimal place.)

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?
