## Unit 5 Learning Outcomes

Upon successful completion of this unit, you will be able to:

• estimate intervals over which the population parameter could exist;
• determine and differentiate between the null and alternative hypotheses in hypothesis testing;
• identify when to use the z and t distributions, and use these distributions to find probabilities;
• test hypotheses of the population mean and population proportion using one or two samples;
• define and apply the significance level, and explain its importance to hypothesis testing; and
• define and determine a region of acceptance based on a test statistic.
