Find the mean, median and standard deviation of these marks. b. Construct the frequency table using interval vidth of 10 marks. C. Create a histogram chart (Present data in a method that can be understood by a non technical audience). d. Find the probability of each age interval and represent that using histogram (Present data in a method that can be understood by a non technical audience). e. From the graph in part d, find the probability that student get a grade of 70 or less and show how you find that on the figure.

Find a. the mean; b. the deviation from the mean for each data item; and c. the sum of the deviations in part (b) for the following group of data items. 157,158,163, 167, 170
Suppose that a polling company surveyed 600 people about how much time they spend watching television each day. The results of this survey were compiled and used to create this relative frequency histogram. Assume that all percentages shown in the histogram are whole numbers. Each of the bars in this histogram includes only the left endpoint of the class except for the last bar, which also includes the right endpoint. What percentage of respondents said that they watch television at least six hours per day? How many respondents said that they watch television between three and five hours per day?
