- Three parts. Look up a z-value, t-value, and chi-square value in the tables using the alpha notation. Example: z(0.05), t(16,0.05), chi-square(12,0.95). (6 pts)
- Two parts. Find the left and right Chi-square critical values for a confidence interval. Look at section 6.4, problems 1c, 2c. Find the sample size when the t-value and level of confidence are known. (4 pts)
- Three parts. Complete a table (1 pt). Determine the degrees of freedom for a given problem (2 pts). Determine the type of sampling used (2 pts). You are given a sequence of clues. Every clue which is necessary is a degree of freedom. Every clue which was unnecessary because you could have figured it out from the other numbers is not. (5 pts)
- Seven parts. Determine standard normal probabilities from the table for each part (2 pts each). Also, sketch the region being asked for in each part (1 pt each). Look at section 5.2, problems 1 - 24. (21 pts)
- Approximate a binomial distribution using the normal distribution. Look at section 5.5, problem 7. (4 pts)
- Two parts. Find the probabilities of events using a non-standard normal distribution. One of these is for an individual score, and the other is for a mean score. Look at section 5.4, odd problems 1 - 19*. (8 pts)
- Find the probability of an event occuring using a non-standard normal distribution. Look at section 5.3, odd problems 9 - 29*. (4 pts)
- Find the cutoff scores for a test if a certain percentage of the class is to receive a certain letter grade. Look at section 5.3, problem 33. (4 pts)
