Homework Answers
Answer:
The mean µ= 0 and the standard deviation σ = 1.
Explanation:
We know that for the standard normal distribution, about 95% of the area under the curve is within ±2 standard deviations of the mean. The mean µ= 0 and the standard deviation σ = 1. Its shape is symmetric bell-shaped.

6. Area under the normal distribution The following figure shows the normal distribution with the proportion of the area under the normal curve contained within one, two, and three standard deviations of the mean. The last proportion on each side, 0.13%, depicts the remaining area under the curve. Specifically, 0.13% of the area under the standard normal distribution is located above z-score values greater than the mean (u) plus three standard deviations (+30). Also, because the normal distribution is symmetrical,...
