The equation of the least squares regression line for predicting total cholesterol from BMIT is cholesterol = 162.56 - 0.9658 ( BMID . The following null distribution was created to test the association between people's total cholesterol number and their BMIL using the slope as the statistic . The null and alternative hypotheses for this test can be written as : Null . No association between cholesterol and BNIT in the population . Alt : Association between cholesterol and BMIT in the population . [ Correlation @ Slope { { -statistic* Mean = 1.0120 SO = 1.625 Mum Samples = 101}} |151 Count 1 15 - 2 - 1 Shuffled Stones i . Based on information shown in the null distribution , how many standard deviations is our observed statistic below the mean of the null distribution ?" (' That is , what is the standardized statistic ?"
