Question 1

Calculate or use a table to find the binomial probability P(x ≥ 20) when n = 25 and p = .5. Also use the normal approximation to calculate the probability.

Question 2

Eight SmartCars were randomly selected and the highway mileage of each was noted. The highway mileage per gallon for each car is shown below:

32 42 29 34 41 37 38 39 40

It was desired to determine if the median miles per gallon of all SmartCars exceeded 35 miles per gallon. Identify the test statistic that should be used when conducting the Sign Test.
◦ S = 2
◦ S = 8
◦ S = 6
◦ S = 38
