If 45 people vote for Arlen Spechter in the primary out of 100, what is the probability that the next person will voter for Arlen Spechter?
Page 25
1. $2.50 x 1400 = $3,500
Page 26
2.
20% x 100 = .20 x 100 = 20
You would expect 20 cars to use the carpool lane.
3.
Low toll - 200
High toll - 800
Page 27
4a.
200 x $1.00 = $200
800 x $4.00 = $3,200
$200 + $3,200 = $3,400
4b.
$3,400/1000 = $3.40
The average toll charge per car will be $3.40
5.
200 cars x 3 = 600 carpool users
800 cars x 1 = 800 non-carpool users
600+800 = 1,400 travelers
6.
The department should make the change because there wil be 400 fewer cars on the road, which will lessen pollution and road wear and be safer.
Page 28
7.
The cars are divided according to the lane they use. The toll for all the cars in each lane is calculated. Then, all the tolls are added.
8a and 8b.
1000 cars
300 cars x $1 = $300
700 cars x $4 = $2,800
$300 + $2,800 = $3,100
Total = $3,100
8c.
$3,100/1000 = $3.10
8d.
The highway department might be interested because they could use this value to estimate the total amount of money collected for different time periods.

3c) Yes, there is a connection. There is a much larger percentage in favor of the bridge on the east side. 58% compared to 38.5%

10)The test was designed in such a complicated way so that it would be easy to determine whether the repellent really works. The group whose lotion contains repellent (experimental group) can be compared to the group whose lotion does not contain repellent (the control group). It is important for people not to know which group they are in so that the results are unbiased.
11a) 200 people
11b) 41 people received repellent and were bitten anyway, 79 people received repellent and were not bitten, and a total of 120 people were given repellent.
11c)
Region 1: With repellent, 34% were bitten; without repellent 66% were bitten
Region 2: With repellent, 64% were bitten; without repellent 64% were bitten
Region 3: With repellent, 77% were bitten; without repellent 70% were bitten
