Course Description: This course is an extension of introductory statistics, primarily for business majors. It investigates methods of collection, organization, presentation, analysis and interpretation of data as tools in effective business decisionmaking. The course covers descriptive and inferential statistics, probability, confidence intervals and hypothesis testing for one and two samples, regression, correlation and chisquare. Computer applications are used to assist in visualizing and analyzing data. This course will also help students gain mathematical literacy which will be of vital significance when making important life decisions. In addition, this course will help with any career that involves applied mathematics, decision making, or problem solving.

2. Construct and interpret confidence intervals for the difference between two population means and proportions.
3. Compute the sample size for the specified margin of error and confidence level.
4. Perform a hypothesis test for one population mean and proportion.
5. Define and apply the concepts of Type I and Type II errors.
6. Compute Type II error probabilities and the power of a hypothesis test.
7. Perform a hypothesis test for two population means and proportions.
8. Perform a hypothesis test for one and two population standard deviations (if time permits).
Outcome 4:Apply analysis of variance and inferential methods in regression and correlation.
1. Use the leastsquares criterion to determine the regression equation.
2. Explain what it means for a set of data to satisfy the assumptions for the regression model.
3. Calculate the standard error estimate.
4. Calculate an estimate for the mean of the population of yvalues that correspond to a particular xvalue.
5. Perform a residual analysis.
6. Perform prediction for an individual yvalue corresponding to a particular xvalue.
7. Perform inferences for the slope of the population regression line.
8. Perform inferences in correlation.
9. Determine Fvalues from the table.
10. Perform the oneway analysis of variance test.
11. Perform a multiplecomparison method.
Outcome 5:Utilize other selected statistic procedures such as multiple regression, chisquare tests, or nonparametric procedures.
1. Perform the chisquare goodnessoffit test.
2. Determine chisquare values from the table.
3. Perform the chisquare independence test.
4. Perform the chisquare test for population standard deviation.
