The superintendent of a large suburban high school must decide whether to close the school for at least two days due to the spread of flu. If she can confirm a trend in absenteeism, then she will close the high school. The following are the number of students absent from the high school on 25 consecutive school days.

44, 56, 55, 40, 42, 51, 50, 59, 58, 45, 44, 52, 52, 43, 48, 58, 57, 42, 60, 65, 69, 75, 70, 72, 72

Use the method of runs above and below the median and α = 0.05 to test the null hypothesis of randomness against the alternative that there is a trend.
