2. Sketch three histograms. One each that demonstrates a skewed-left distribution, a skewed-right distribution, and a bell-shaped distribution. For each one, state the relationship between the mean, median, and mode. Explain your reasoning
6. A distribution has a shape that is strongly skewed left. Which of the following statements is most likely true about this distribution? (A) Mean > Median (B) Mean = Median. (C) Mean < Median. (D) Only the mode can be determined. (E) There are no outliers in the distribution. Submit Answer
Given the typical form of the distribution of ages at death is left skewed: a. The median will be greater than the mode b. The median will be greater than the mean c. Most of the values are concentrated on the left hand side of the distribution d. The mean is the most appropriate measure of central tendency
