Use MINITAB or some other software program to regress the marine growth on freshwater growth for the fish growth data in Table D.7 of the Data Bank. Do separate regression analyses for:
(a) All fish.
(b) Males.
(c) Females.
Your analysis should include (i) a scatter diagram, (ii) a fitted line, (iii) a determination if β1 differs from zero. Also (iv) find a 95% confidence interval for the population mean when the freshwater growth is 100.
