You need to Decide which professor to take the class from and have just completed your introductory statistics course. Records obtained from the past students indicated that students in professor alphas class have a mean score of 80% with a standard deviation of 5%, while past students in professor Omega's class have a mean score of 80% with a standard deviation of 10%. Decide which professor to take for introductory biology using a statistical argument.
