Suppose that public opinion in a large city is 55% in favor of increasing taxes to support renewable energy and 45% against such an increase. If an interview of a random sample of 600 people from this city is conducted, what is the approximate probability that more than 360 of these people will be against increasing taxes?

A. 600 choose 360 times 0.55 to the 360 power times 0.45 to the 240 power.

B. Probability of z greater than quantity 0.60 minus 0.45 end quantity over square root quantity of 0.45 times 0.55 over 600 end quantity.

C. Probability of z greater than quantity 0.60 minus 0.55 end quantity over square root quantity of 0.55 times 0.45 over 600 end quantity.

D. Probability of z greater than quantity 0.60 minus 0.45 end quantity over square root quantity of 0.60 times 0.40 over 600 end quantity.

E. 600 choose 360 times 0.45 to the 360 power times 0.55 to the 240 power.

An annual marathon covers a route that has a distance of approximately 26 miles. winning times for this marathon are all over 2 hours. the following data are the minutes over 2 hours for the winning male runners over two periods of 20 years each. earlier period 14 12 15 22 13 10 19 13 9 14 20 18 16 20 23 12 18 17 6 13 recent period 7 11 7 14 8 9 11 14 8 7 9 8 7 9 9 9 9 8 10 8 (a) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the earlier period. use two lines per stem.
