Find an estimate for the mean and stan- dard deviation of the data. (Use the mid points) Construct a cumulative frequency table for the data and draw a cumulative fre- quency graph. (Use the upper bounds) Using the graph, estimate the semi- interquartile range for the data. Using interpolation, find the median of the data.
