Question

the time it takes to drive from Orangeville to the Vaughan Mills Mall is normally distributed with a mean of 52 minutes and standard deviation of 5 minutes. What intervals could you estimate without using the Z-score table and that do not include the mean as a max or min? For example, is an interval we know that includes the mean as the maximum of the interval. Another example is as an example of a probability interval that includes the mean as the minimum and 57 as the maximum. Include at least 7 intervals, their probabilities and a sketch in your answer.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
