Text: Custom Extraction from Miller, C. D., et al. Mathematical Ideas, twelfth edition.

- first lecture - p.116[636]: 1ab (N.B.: you should construct a bar chart, not a
histogram), 23, 24, 36 (in this context probabilities are relative
frequencies);

Also: Which of the following can be displayed with a pie chart? populations of the states, years since admission of the states, per capita incomes of the states - second lecture - p.117[637]: 5ab, 9;

Also: Which of the following are quantitative (versus qualitative) charaters? height, eye color, hometown, type of pizza, weight, age - third lecture - p.130[650] - 1, 9 (also find the maximum, minimum, and
midrange), 13, 15, 19,
20, 21, 22, 23, 24, 31, 33, 34, 35, 36, 47 (also midrange), 49, 51;

Also: If you drive 10 miles at 30 mph and 10 miles at 50 mph, what is your average speed?

If you put $100 in the bank for two years and it earns 3% interest the first year and 5% interest the second year, what is the average interest rate? - fourth lecture - p.139[659] - 3, 5, 29, 30, 31, 32; p.139[659] "For Further Thought" 1, 2; p.155[675] - 9, 13 (I am only interested in the empirical rule from this section)
- fifth lecture - p.145[665] - 1, 2, 5, 13, 18, 19, 22, 23, 25, 31;

Also: If the mean weight in a class is 148 pounds, and the standard deviation is 34 pounds, what is the z-score of a 175 pound student? - sixth lecture - p.140[660] - 41, 42, 45; p.146[666] - 23, 25, 26; Also: What does the height of a bar in a histogram tell you? The width? The area?, What does the height of a box in a box-and-whisker plot tell you? The width? The area?

- ninth lecture - p.7[531] - 1, 3, 11, 21, 23, 49, 57, 59, 60, 63; p.17[541] - 27, 29, 35, 36, 37, 39, 40, 45, 47, 53, 59, 61

- eleventh lecture - p.36[560] - 5, 10, 15, 23, 25, 27; p.36[560] "For Further Thought" 3, 5
- twelfth lecture - p.63[585] - 8, 11, 12, [for 55 and 56, assume there are three men and three women] 55, 56, 59, 65; p.72[594] - 4, 7, 9, 11,
13, 15, 17, 23, 25;

Also: If P(A) = .4 and P(B) = .6, and A and B are mutually exclusive (disjoint), P(A ∩ B) = ? P(A ∪ B) = ? (If symbols are missing, they are union and intersection signs; the question marks after the equal signs are question marks) - thirteenth lecture - p.81[603] - 5, 6, 9, 11, 13, 17, 19, 23, 25, 29, 30, 35 [there are problems with the wording of this problem, you must assume independence of gender of subsequent births and no gender bias in mortality],
52;

Also: If P(A) = .4 and P(B) = .6, and A and B are independent, P(A ∩ B) = ? P(A ∪ B) = ? (If symbols are missing, they are union and intersection signs; the question marks after the equal signs are question marks)

- fourteenth lecture - p.65[587] - 46, 49 (do not refer to table 1);

Also: What is the probability that two face cards which are drawn from a standard 52 card deck are both black if they are drawn without replacement? If they are drawn with replacement?

Fairness and Election problems [start with the 8th bullet on scoring a track meet]

Music/dance problems? [Not covered this semester]
