Discrete Random Variables – Mean Answers

Which histogram shows data that can be idealized with a Normal curve?

Based on the model (curve) provided we can estimate that the mean is μ = ºF, that the curve changes concavity around a value of ºF, which is ºF below the mean, so the standard deviation of this distribution is approximately σ = ºF.
