What is the probability that a randomly selected day from 2013 will have a Group Trades total within 101,000 of the mean? Mean: 3421439 St Dev: 508638.08

Question

I'm trying to apply it to Stat Crunch on the Normal Calculator, but I don't know what number I should use. Is it P(mean/101,000)?

Answer 1

Use the Stat Crunch Normal Calculator with:

µ=3421439

σ=508638.08

lower limit=3421439-101000

upper limit=3421439+101000
