a) 0.09

b) 0.66

c) 0.71

d) 0.92

2) Walleye is a common game fish. Adult walleye have a length with a mean of 48 cm and a standard deviation of 3 cm and the distribution of lengths is approximately normal. What length corresponds to the 25th percentile of fish lengths?

a) 41 cm

b) 46 cm

c) 44 cm

3) For which of the following counts would a Poisson probability model be reasonable?

a) the number of days in a pregnancy

b) the number of detective parts produced by a machine in a lot of 1,000

c) the number of complaints a cashier receives per hour

d) the weight of a randomly selected baby

4) Historically, about 52% of newborns are male. A sample of 1,000 babies downwind from a smelter finds that 55.2% were male. What is the probability of seeing 55.2% or more of babies being male if the smelter had no effect on the sex ratio?

a) 0.51

b) 0.02

c) 0.09

d) <0.001

5) In a test of ESP (Extrasensory perception), the experimenter looks at cards that are hidden from the subject. Each deck of 60 cards contains equal numbers of cards with a star, a circle, and a wavy line, or a square. An experimenter looks at each of the 60 cards in turn, and the subject tries to read the experimenter's mind and name the shape on each. What is the standard deviation of the number of correct responses if the subject does not have ESP?

a) 15

b) 5.25

c) 3.35

d) 1.33

6) A large colony of 100 mice has a 52:48 (M:F) sex ratio. In a random sample of 8 mice, the number of mice that are male should have a:

a) Binomial distribution with n = 100 and p = 0.50

b) Binomial distribution with n = 100 and p = 0.52

c) Binomial distribution with n = 8 and p = 0.52

d) Binomial distribution with n = 10 and p = 0.60
