The answer is D
To solve the answer you would have needed to multiply the reciprocal of 
but in this case, Unvi multiplied with the reciprocal of 14.
X^2 = 150
√x^2 = √150
x = 5√6 (or) ≈12.25
HOPE THIS HELPS!!!!
1. Answer: given: an average of 28 pounds
a.
Find z values corresponding to 27 and 31:
z=%2827-28%29%2F2=-1%2F2=-0.5
z=%2831-28%29%2F2=3%2F2=1.5
Find the area between z+=+-0.5 and z=+1.5
Table E gives us an area of 0.9332-0.30=0.6247=> The probability is 62.47%
b.
Find z values corresponding to 30.2
z=%2830.2-28%29%2F2=2.2%2F2=1.1 Find the area to the right of z+=1.1
it gives you an area of 0.1357=> The probability is 13.57%
I think the answer is: a score of <span>38 on a test for which = 27 and s = 10</span>
