A friend of yours has 20 min to get to their after-school job. Despite their best efforts, they are frequently late and have been tracking how long it takes (in minutes) to get there.
Their recorded times are as follows: {18, 20, 22, 27, 16, 23, 25, 26, 19, 28}.
a) Determine all measures of central tendency for the list of travel times—mean, median and mode.
b) Which measure of central tendency do you think best represents the ‘average’ time it takes your friend to get to work? Justify your choice.
c) Create a histogram that represents the list of travel times. You may use the grid (template; next page) provided or create your own.
d) Classify your distribution as either normal, uniform, bimodal, or skewed (left or right). Explain your choice.
e) Determine the range for the list of times.
f) Determine the standard deviation for the list of times. Organize some of your calculations in the sample table provided. Show all remaining calculations that it takes you to determine the standard deviation.
