Suppose that public opinion in a large city is 60% in favor of increasing taxes to support the alternatives to drug addiction treatment and 40% against such an increase. If an interview of a random sample of 400 people from this city is conducted, what is the approximate probability that more than 150 of these people will be against increasing taxes? 400 choose 150 times 0.60 to the 150 power times 0.40 to the 250 power.
400 choose 150 times 0.40 to the 150 power times 0.60 to the 250 power.
Probability of z greater than quantity 0.375 minus 0.60 end quantity over square root quantity of 0.60 times 0.40 over 400 end quantity.
Probability of z greater than quantity 0.375 minus 0.40 end quantity over square root quantity of 0.40 times 0.60 over 400 end quantity.
Probability of z greater than quantity 0.375 minus 0.40 end quantity over square root quantity of 0.375 times 0.625 over 400 end quantity.
