# Question

a. State an approximate value for the mean height by looking at the graph.

b. Here is a proposed method for finding an approximation for the standard deviation based on the histogram: Find the approximate range and divide by 6. This method comes from the idea that nearly all the data should be within 3 standard deviations of the mean. Use this method to find an approximate standard deviation.
