Let X represent the full height of a certain species of tree. Assume that X has a normal probabilitydistribution with mean 151.4 ft and standard deviation 21.9 ft.You intend to measure a random sample of n = 126 trees. The bell curve below represents thedistribution of these sample means. The scale on the horizontal axis is the standard error (standarddeviation) of the sampling distribution. Complete the indicated boxes, correct to two decimal places.Submit QuestionupCe23&68.eyfgedi

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.
