We want to estimate the mean score p in the population of all young men. Consider the NAEP sample as an SR5 from a Normal population with standard deviation o = 60. According to the 95 part of the 63-95-995." rule {the empirical rule}, 95% of all values of :7: with a sample size of 840 fall within _ on either side of the unknown mean p. What is the missing number? Round to 4 decimal places
