QUESTION 3 On an American roulette table, there are 38 squares that correspond to 38 slots in the roulette wheel. You can bet on single squares or combinations of squares. Each square has a number and a color. Eighteen of the squares are red, 18 are black, and 2 are green. One thing you can do is bet red (or black), and it pays even money. (You risk $1, but if the roulette lands on any red space, you get back your $1 plus $1 in winnings.) If you play 30 times, betting $1 on red each time, what is the probability you will come out ahead? O 0.64 O 0.36 O 0.50 O None of the above. QUESTION 4 A box has many, many numbered tickets. A simple random sample of 500 tickets from the box has an average of 47 and a standard deviation (SD) of 12. Set up an approximate 95% confidence interval for the average of the whole box. [45.92, 48.08] O [-489.66, 583.66] [-1, 95] [43.74, 58.33] QUESTION 5 A simple random sample of 200 people in a large town has an average education level of 11.8 years with a standard deviation of 4. 1 years. Set up an approximate 90% confidence interval for the average education level of everyone in the town. O [24.14, 32.55] [82.26,87.74] [20.94,31.06] O [11.305, 12.295]
