Please do not use excel, answer 2-5
Select the statements that describe a normal distribution. Two parameters define a normal distribution—the median and the range. The density curve is symmetric and bell‑shaped. The normal distribution is a discrete distribution. The normal distribution is a continuous distribution. Approximately 5%5% of values fall more than two standard deviations from the mean. The density curve is left‑skewed.
