+4 Suppose that shoe sizes of American women have a bell-shaped distribution with a mean of 8.35 and a standard deviation of 1.47. Using the empirical rule, what percentage of American women have shoe sizes that are at least 6.88? Please do not round your answer
+37157 See a similar Question that I answered here:
https://web2.0calc.com/questions/americam-women-shoe-size
8.35 - 1 S.D. = 6.88 which means 34.1 + 50 % = ~84.1% have a shoe size 'at least' 6.88 ~15.9% have a shoe size less than 6.88
(The problem wording is 'at least' 84.1% have a shoe size BIGGER than 6.88 <======is that what 'at least' means here? )
