Chapter 8 29. The travel-to-work time for residents of the 15 largest cities in the United States is reported in the 2003 Information Please Almanac. Suppose that a preliminary simple random sample of residents of San Francisco is used to develop a planning value of 6.25 minutes for the population standard deviation. If we want to estimate the population mean travel-to-work time for San Francisco residents with a margin of error of 2 minutes‚ what sample size should be used? Assume 95% confidence

deviations of the mean - Virtually all‚ 99.7% of the area under the curve is within +/- 3 standard deviations of the mean Is a z-score the distance between a selected value (X) and the population mean (u) divided by the population standard deviation(s)? Yes. We use z-scores to change normal probability distributions into standard normal probability distributions‚ which are unique because they have a mean of 0 and standard deviation of 1. To convert to a standard normal probability distribution
