In the casino game roulette, if a player bets $1 on red, the probability of winning $1
Chapter 6, Problem 6.1-5(choose chapter or problem)
In the casino game roulette, if a player bets $1 on red, the probability of winning $1 is 18/38 and the probability of losing $1 is 20/38. Let X equal the number of successive $1 bets that a player makes before losing $5. One hundred observations of X were simulated on a computer, yielding the following data:
23 127 877 65 101 45 61 95 21 43
53 49 89 9 75 93 71 39 25 91
15 131 63 63 41 7 37 13 19 413
65 43 35 23 135 703 83 7 17 65
49 177 61 21 9 27 507 7 5 87
13 213 85 83 75 95 247 1815 7 13
71 67 19 615 11 15 7 131 47 25
25 5 471 11 5 13 75 19 307 33
57 65 9 57 35 19 9 33 11 51
27 9 19 63 109 515 443 11 63 9
(a) Find the sample mean and sample standard deviation of these data.
(b) Construct a relative frequency histogram of the data, using about 10 classes. The classes do not need to be of the same length.
(c) Locate \(\bar x, \bar x \pm s, \bar x \pm 2s\), and \(\bar x \pm 3s\) on your histogram. (d) In your opinion, does the median or sample mean give a better measure of the center of these data?
