a. find the mean and standard deviation of the following set of ungrouped sample data: 4, 3, 5, 2, 3, 1, 2, 5, 3, 1, 5, 4, 6, 4, 5, 1, 3, 3, 7, 8, 7, 5, 4, 3, 7, 8, 4, 6, 9, 10, 10, 9, 6, 4, 6.

b. What proportion of the measurements lies within one standard deviation of the mean? Within two standard deviations of the mean? Within three standard deviations?

c. Based on part (b), would the histogram for this data be “bell-shaped”? Explain.
