The Binomial Distribution - Math is Fun
μ = 3.6 ... Variance: σ 2 = 13.32 − 3.6 2 = 0.36 Standard Deviation is: σ = √ (0.36) = 0.6 And we got the same results as before (yay!)
Normal Distribution - Math is Fun
first subtract the mean: 26 − 38.8 = −12.8, then divide by the Standard Deviation: −12.8/11.4 = −1.12 ... From the big bell curve above we see that only 0.1% are less. But maybe that is too small. ... Below …
