The answer is 459 </h2>
97.5% of American women have shoe sizes that are no more than 11.47.
Lets try to solve the question,
Given values ,
Dev (u) = 8.47
Standard deviation (x) = 1.47
So we e have to find the percentage of American women whose shoe size's are not more than 11.47 P(x<11.47).
Lets find z score by using empirical formula.
=> 
=> 
=> 
Now we have to find
. Using the empirical rule, we know that 97.5% data lies below 2 standard deviations above mean.
Therefore the 97.5% of American women have shoe sizes that are no more than 11.47.

a3=9
assuming the pattern is constant, a3 is right in the middle of a1 and a5 so the answer would be right in the middle of 6 and 12. the average of 6 and 12 is 9, so a3=9.
