7 Answers to Textbook Review

8 Or 1 – geometcdf (.1, 3) = 0.729

9 E49. a. 1- binomcdf (20, 0.80, 9) = 0.9994 b. 1 – binomcdf (20, 0.65, 9) = 0.9468 This is assuming the region has the same statistics reported for the rest of the country. c. For both girls and boys (0.8 + 0.65)/2 = 0.725 So combined 1 – binomcdf(40,0.725, 19) = 0.99928

10 E54. a. Assumptions: First I have to assume that all 5 athletes are equally likely to be found in each of the cereal boxes. Model: I am assigning each of the following digits to the 5 athletes. I am going to pretend that the athlete I want is Athlete 1.

11 b. (geomcdf 0.2, 4) = 0.5904 c. Expected a # is 1/0.2 = 5. It will be on average 5 boxes on average to get the desired poster. d. For the first of one of the two athletes it would be 1/(2/5)= 2.5 boxes + 1/.2 for the second box so it will take 7.5 boxes. AP 1) B 2) B 3) C 4) D

12 Feedback on H.W. 6.1 D7 I gave you specific directions to solve for the distribution how you would normally would. This means writing out the probability distribution and finding the mean and std. dev. The second way was describe a simulation. You had to state how you would carry it out. Stating assumptions and your model, and how you would carry out the repetitions. If you got less than a 90%, you can come in during 7 th block today or tomorrow to make corrections and I will give you partial credit back, BUT only if you do them in this class during 7 th block.

13 Warm-up Day of Ch. 6 Practice Test 4% of people have AB blood. What the probability that there is a Type AB donor among the first five people checked? I understand why you use the geometcdf(0.04,5) to calculate the probability of finding success on or before the 5 th person. But what I don’t understand is why you can’t also use binompdf (5,0.04,1) to find the probability of one success in five people. This was a question posted on A.P. Statistics teacher mailing list.

14 Ch. 6 Practice Test Answers 1)B (pg 371 and 372 show the rules) 2) E (Law of Larger Numbers) 3) C mean 42 (times 1.5 + 7 ) = 70 new mean variance 9 (1.5 2 ) then square root for S.D. 4)C = 4 (1/6) + 0.5 (1/6) - 1 (4/6) = 0.08 5)C = -1000(0.13) + 1000(0.24) + 2000(0.35) + 3000 (0.13) Free Response 1.a. 0.651 1 – binomcdf(10,.1,0) b. 0.549 1 – binomcdf (100,.1,9) c. 0.04 1 – binomcdf (100,.1, 15) d. 0.729 2. a. 24 outcomes

15 Remaining Practice Test Answers b. Sample space: {(1, 1) (1, 2) (1, 3) (1,4) (2, 1) … (6, 4)} c. 6/24 = ¼ d.2/24 = 1/12 e. Not disjoint b/c (2,2) is a double and a sum of 4. Not independent P(4 l Doubles) = P(4) A. P. Statistics: 5 multiple choice questions and 3 free response Statistics : 5 multiple choice questions and 2 free response

16 Rules for Transformations and addition and subtraction of Data
