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?
[First Test]
- 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

- 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?
[Second Test]
