Frequency distribution, histogram and stem-and-leaf

For following set of scores, prepare a frequency distribution, a histogram, and a stem-and-leaf display for each variable. Also calculate the mean, the median and the standard deviation of each score. Are there any outliers in the distribution? If so,what is the result if these scores are removed fro the data set? Draw a scatterplot that illustrates the relationship between the two variables.
