Q:
# On average, junior girls own 10 pairs of shoes with a standard deviation of 1.5 pairs of shoes. the distribution of shoes follows an approximately normal curve. what is the probability of selecting a junior girl that owns 12 or more pairs of shoes

Accepted Solution

A:

solve for z score:

z(12)=(12-10)/1.5=4/3

then >/ "less than and equal to"

p(x>/12) = p(z>/4/3)=.0912

z(12)=(12-10)/1.5=4/3

then >/ "less than and equal to"

p(x>/12) = p(z>/4/3)=.0912
