According to a new survey from the Boston Indicator.org website, Boston city schools had an average of 3.6 students per computer for the 2007€“2008 school year. The average was the same for the whole state of Massachusetts but higher than the average for any of the suburban districts. A sample of Boston city schools reported their average number of students per computer in the sequence that follows:

a. Determine the median and the number of runs above and below the median.
b. Use the runs test to test these data for randomness about the median. Use a = 0.05.
