Text: Miller, C. D., et al. Mathematical Ideas, eleventh edition.

• first lecture - p.788: 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.789: 5ab, 9;
  Also: Which of the following are quantitative (versus qualitative) charaters? height, eye color, hometown, type of pizza, weight, age
• third lecture - p.803 - 1, 9 (also find the maximum, minimum, and midrange), 11, 19, 20, 21, 22, 23, 24, 31, 34, 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.814 - 3, 5, 29, 30, 31, 32; p.814 "For Further Thought" 1, 2; p.832 - 9, 13 (I am only interested in the empirical rule from this section)
• fifth lecture - p.821 - 1, 5, 6, 18, 19, 29, 32;
  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.816 - 41, 42, 45; p.822 - 23, 25, 26; p.841 - 5, 6 (I included 5 and 6 so you would think about whether height or area reflects relative size), 12, 15
  

• ninth lecture - p.678 - 1, 3, 11, 21, 23, 49, 61, 62, 65; p.689 - 31, 37, 38, 39, 41, 42, 48, 49, 61, 62
• tenth lecture - p.689 - 4, 7, 11, 15, 17, 19; p.702 - 1, 3, 19, 21, 24, 25, 27, 29, 34, 35, 39, 41, 43, 47, 49, 60
• eleventh lecture - p.710 - 5, 10, 15, 23, 25, 27; p.709 "For Further Thought" 3, 5
• twelfth lecture - p.731 - 8, 11, 12, 55, 56, 58, 65; p.742 - 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.752 - 5, 6, 9, 11, 13, 17, 19, 23, 25, 29, 30, 36, 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.731 - 46, 49;
  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

Music/dance problems? [Not covered this semester]

[Third Test]

• twenty-fifth lecture - p.864 - 1, 3, 5, 7a, 9a, 29
• twenty-sixth lecture - p. 864 - 7b, 9b, 21, 23, 25abcd, 33, 35, 41, 43
• twenty-seventh lecture - p. 864 - 25e, 55, 57, 59
• twenty-eighth lecture - p.873 - 1, 3; p.887 - [1, 3, 17 (They want you to use table 6 to find the APR)] 17a (I do not think that using table 6 is important); p.899 - 1, 5, 9, 13, 21, 22, 23, 24, 31, 33
