 Objectives

Ch 11

1. State the 2 assumptions for drawing inferences about a population mean when sigma is not known.

• SRS

• Normal Distribution of the population

1. Calculate standard error (standard deviation of the sampling distr. = s/n^.5) for a sample.

2. Explain when a t statistic is used rather than a z score.

3. Calculate t statistics.

4. State the degrees of freedom for a t test.

5. Construct confidence intervals using the t statistic.

6. Perform one sample t-procedures on the TI-83.

 Ch State the assumptions made for two sample tests. (p. 619) Create confidence intervals and hypothesis test using two sample t procedures assuming that the sigmas of the two populations are unequal. This is the most concervative assumption. Be aware of the more accurate way to calculate df as shown on page 633. Perform two sample hypothesis t-procedures on the TI-83. State the key assumption required for using the pooled two-sample t-procedures. The sigmas of the two populations are the same Home Work 11.33, 11.35, 11.37, 11.49:
