9. A microchip manufacturer produced the chipset NO-RM41. In the prototyping phase, the
following data were gathered about optimal clock speeds for the batch of sample chipsets:
Clock Speed (MHz)
0-200
200-400
400-500
500-600
600-700
700-1000
Frequency

(a) Find the mean, the median, and the modal class for optimal clock speeds.
(b) Find the interquartile range and produce a box-plot of these data. Comment on any
relevant features of the shape of the plot.
(c) Calculate the standard deviation of clock speeds.
(d) Calculate a value for the skewness of these data. Comment on the extent to which
this value supports your comment in part b).
