Perform a regression predicting pre-dorsal length based on body depth. True or false: the 95% confidence interval for the slope estimate overlaps 0?

Create a contingency table for the HairEye_all dataset. Conduct a chi-squared test on this data set. True or false: based on your chi-squared statistic and associated p-value, there is an association between eye color and hair color.   Note: You will not be using a correction in this case (i.e., correct = FALSE)

Create a contingency table from the HairEye_short data set. Conduct a chi-square test on the HairEye_short data set. True or false: based on your chi-squared p-value, there is an association between hair color and eye color.
