 Using the normal distribution

Card 10 / 25:
According to a study done by De Anza students, the height for Asian adult males is normally distributed with an average of 66 inches and a standard deviation of 2.5 inches. Suppose one Asian adult male is randomly chosen. Let X = height of the individual.
X ~ _____(_____,_____)Find the probability that the person is between 65 and 69 inches. Include a sketch of the graph, and write a probability statement.Would you expect to meet many Asian adult males over 72 inches? Explain why or why not, and justify your answer numerically.The middle 40% of heights fall between what two values? Sketch the graph, and write the probability statement.

mean is number that occurs frequently in a giving data
That places the mode and the mean as the same thing. I'd define the mean as the ratio of the total sum of variables to the variable count, and it assigns the variables a similar value across the board.
