The variables of interest were body weight in grams and heart weight in grams. It was desired to develop a linear regression equation in order to determine if there is a significant linear relationship between heart weight and total body weight. Use this information to answer the questions. Click the icon to view the table of woodchuck body weights and heart weights. Use heart weight as the independent variable and body weight as the dependent variable and fit a simple linear regression using the given data. y= 3973+ (-66.1)x (Round the constant to the nearest integer as needed. Round the coefficient to one decimal place as needed.) Test the hypothesis Ho: B₁ = 0 versus H₁: B₁ #0. Is the test one-tailed or two-tailed? two-tailed one-tailed Determine the test statistic. t= (Round to two decimal places as needed.)
