The characters aren't displaying properly..

1.96sigma = 5500 - mu
2.3263sigma = mu - 3500

Didn't double check this now but this should be the solution..

1.96sigma = 5500 - mu
2.3263sigma = mu - 3500

mu = 5500 - 1.96sigma
mu = 2.3263sigma + 3500

5500 - 1.96sigma = 2.3263sigma + 3500

2000 = 2.3263sigma + 1.96sigma
2000 = 4.2863sigma
sigma = 2000/4.2863 = 466.603

mu = 5500 - 1.96*466.603
mu = 4585.46

sigma = 466.603
mu = 4585.46
