The Pew Research Center reported that 57% of Americans favored the Wall Street bailout of 2008. A random sample of 300 people showed that 155 people favored the bailout. If appropriate, test whether the population proportion of Americans is different from 57%. Use level of significance a = 0.01. What if we cut the sample size down to between 150-160 people, and we cut the sample number of successes as well, so that the sample proportion p stayed the same? Suppose that everything else stayed the same. Describe what would happen to and the conclusion.
would remain the same and so would the conclusion.
would increase and the conclusion would change.
