Just want to check that I am on the right track:

Find the probablility that "a" is greater than 0%

mean = 13.4%
standard deviation = 20%
Z = (0 - .134)/.205
Z = (-.134) / .205
Z = -0.6537
Probability from Distribution table = 0.2422 (24.22%)
Therefore my answer would be .2422 + .5000 = .7422 or 74.22%? :confused:

Thanks for any guidance you can provide:wave:
