1. If a distribution appears to be bell-shaped and symmetric about its mean, can we assume that the probability of being within one standard deviation of the mean is .68?

2. Can two distributions differ by a large amount yet have equal means and variances?

3. If a distribution is skewed, is it possible that the mean exceeds the .85 quantile?

Explain in what sense the population variance is sensitive : For normal random variables, the probability of being within one standard deviation of the mean is .68. That is, P(µ - σ ≤ X ≤ µ + σ) = .68 if X has a normal distribution. For nonnormal distributions, is it safe to assume that this probability is ..
