A survey of B2B marketers (marketers that focus primarily on attracting businesses) and B2C marketers
(marketers that primarily target consumers) was based on 1000 B2B marketers and 1000 B2C marketers. The

a. Suppose you know that the marketer is a B2B marketer. What is the probability that he or she plans to increase use of social media?
The probability that he or she plans to increase use of social media is
(Simplify your answer. Round to three decimal places as needed.)
b. Suppose you know that the marketer is a B2C marketer. What is the probability that he or she plans to increase use of social media?
The probability that he or she plans to increase use of social media is
(Simplify your answer. Round to three decimal places as needed.)
c. Are the two events, increase use of social media and business focus, independent? Explain.
O A. No, because the probability that the marketer plans to increase social media use given the marketer type is not the same as the probability that a marketer plans to increase social media use.
OB. No, because the probability that the marketer plans to increase social media use is not the same as the probability that the marketer is a B2C marketer.
nC. Yes. because the probabilitv that the marketer plans to increase social media use aiven the marketer tvoe is not the same as the probabilitv that a marketer olans to increase social media use

A professional golfer is shopping for a new brand of golf ball. She likes most of the features of one particular brand, but she wants to make sure that the brand has a desirable spin rate (the rate at which the ball spins on its axis after being struck by a golf club). To test the spin rate of this new brand of ball, the golfer hits the brand of ball on 76 shots, and a computer measures the spin rate for each shot. The computer then produces the following histogram summarizing the 76 spin rates. 25 20 15 10 5 0 Frequency 4 12 13 22 19 6 5000 5500 6000 6500 7000 7500 8000 Spin rate (in revolutions per minute) Based on the histogram, estimate the mean spin rate (in revolutions per minute) for the sample. Carry your intermediate computations to at least four decimal places, and round your answer to the nearest integer.

Marine biologists have noticed that the color of the outermost growth band on a clam tends to be related to the time of year in which the clam dies. A biologist conducted a small investigation of whether this is true for the species Protothaca staminea. She collected a sample of 50 clam shells in February and 27 clam shells in March. 15 of the shells from February had a dark color on the outermost growth band, whereas 8 of the shells from March had a dark color on the outermost growth band. Carry out a hypothesis test to see if there is a difference in the proportion of shells with a dark outermost growth band between the two months. The point estimate for the true difference in proportion of dark growth bands between February and March is:
