The daily revenue from the sale of fried dough at a local street vendor in boston is known to be normally distributed with a known standard deviation of $120. the revenue on each of the last 25 days is noted, and the average is computed as $550. a 95% confidence interval is constructed for the population mean revenue. if the data from the last 40 days had been used, then the resulting 95% confidence intervals would have been multiple choice narrower, with a larger probability of reporting an incorrect interval wider, with the same probability of reporting an incorrect interval narrower, with the same probability of reporting an incorrect interval wider, with a larger probability of reporting an incorrect interval next
