You have just been hired by the Boston Marketing Company to conduct a survey to estimate the mean amount of money spent by movie patrons (per movie) in Massachusetts. First use the range rule of thumb to make a rough estimate of the standard deviation of the amounts spent. It is reasonable to assume that typical amounts range from $10 to about $35. Then use that estimated standard deviation to determine the sample size corresponding to 98% confidence and a $0.25 margin of error.
