Objectives

1. Employ sampling techniques to collect data and summarize data using graphs and descriptive statistics.
2. Solve counting and probability applications.
3. Determine whether or not a variable conforms to a particular probability distribution including the binomial distribution, normal distribution, F-distribution or t-distribution.
4. Compute confidence interval estimates and perform hypothesis tests pertaining to one and two samples. Test multiple samples via analysis of variance.
5. Perform a linear regression analysis.
