(Hypothetical.) A bank wants to estimate the amount of change people carry. They take a simple random sample of 100 people, and find that on the average, people in the sample carry 73$\Phi$ in change. They figure the standard error is 4$\phi$ , because $$ \sqrt{100} \times \sqrt{0.73 \times 0.27} \approx 4, \quad 4 / 100=.04 $$ Are they right? Answer yes or no, and explain.
