A research analyst disputes a trade group’s prediction that back-to-school spending will average $622 per family this year. She believes that average back-to-school spending will significantly differ from this amount. She decides to conduct a test on the basis of a random sample of 35 households with school-age children. She calculates the sample mean as $637. She also believes that back-to-school spending is normally distributed with a population standard deviation of $68. Calculate the test statistic. Keep three decimals
