An srs of 350 350 high school seniors gained an average of ¯ x = 22.61 x¯=22.61 points in their second attempt at the sat mathematics exam. assume that the change in score has a normal distribution with standard deviation σ = 53.63 . σ=53.63. we want to estimate the mean change in score μ μ in the population of all high school seniors. (a) using the 68 68 – 95 95 – 99.7 99.7 rule or the z - z- table (table a), give a 95 % 95% confidence interval ( a , b ) (a, b) for μ μ based on this sample.
