We worked two long example problems text and compared the P-Value and Critical Value methods of hypothesis testing. We started by "translating" the statement of the problem into Null Hypothesis and Alternative Hypothesis. We associated sample distributions with the parameter being examined.

We spent much of the session comparing two methods of hypothesis testing illustrated in a text book example problem. We spent the remainder of the period discussing and comparing Type I and Type II errors .

We examined Section 8.3 in the text, extensive example problems in setting up null and alternative hypotheses, finding the test statistic, and Type I and Type II errors.

We discussed the formulation of Null Hypotheses and Alternative Hypotheses. We went over translating a word problem (homework assignment) into hypotheses and relevant formulas reject/fail to reject the null hypothesis.

N/A. Pablo was absent.

We worked through several examples from Chapter 6 of the text, including some interesting problems on bone density testing, size hiring limits for flight crews and ceiling height in passenger cabins of airplanes. These involved making connections between scores and probabilities. We also found probabilities of non-standard normally distributed values by converting them to z-scores and finding the associated probability from a standard normal table.

We discussed how area under a probabiluity density function curve is equal to one and why. I emphasized the correlation between area under the curve and probability. We worked through a number of example problems in the text.

Review for his test tomorrow. Review of binomial distribution, normal distribution and probability.

He was struggling with normal distribution curves and how to calculate probabilities and percentages from them.

Devon will be prepared for her test. She must be able to find confidence intervals for means and proportions.
