(18.02) A survey of licensed drivers inquired about running red lights. One question asked, "Of every ten motorists who run a red light, about how many do you think will be caught?" The mean result for 807 respondents was x¯¯¯ = 2.1 and the standard deviation was s = 1.92. For this large sample, s will be close to the population standard deviation s, so suppose we know that s = 1.92. Give a 95% confidence interval (±0.01) for the mean opinion in the population of all licensed drivers: ± .
