A wildlife analyst gathered the data in the table to develop an equation to predict the weights of bears. He used WEIGHT as the dependent variable and CHEST, LENGTH, and SEX as the independent variables. For SEX, he used male=1 and female=2. Using Microsoft Excel, perform a regression analysis and find R-squared, adjusted R-squared, and the p-value for the regression. y=dependent x=independent

Weight	Chest	Length	Sex
344	45	67.5	1
416	54	72	1

Expert Solution

Regression equation: y = -442.60+12.13X1+3.58X2-23.84X3

R-squared = 0.93

adjusted R-squared = 0.90

and the p-value (Significance F) = 0.000066

1. Obtain a linear regression equation for the data to predict the mean temperature values for any given CO2 level. How good is the linear fit for this data? Explain using residual plot and R-square value. To draw residual plot, compute the estimated temperatures for every value of the CO2 level using the regression equation. Then compute the difference between observed (y) and estimated temperature values (called residual; ). Plot the residuals versus CO2 level (called a residual plot). 320.09...
