An introduction to statistical inference and sufficient probability theory for such an introduction. Topics include elementary data analysis, elementary probability, discrete and continuous random variables, distributions (including the normal distribution), correlation and regression, sampling distributions, point and interval estimation, confidence levels, and tests of significance. Students may not receive credit for successful completion of MATH 111 and MATH 113. They may receive a total of seven hours of credit for successful completion of a combination of MATH 111 and BIOL 350, or MATH 113 and BIOL 350. However, the two statistics courses may not be used together to fulfill the collegiate requirement in mathematics. C21:NS,QS.
