Number of larvae Frequency (Number of squares) 13 0 1 34 2 50 3 18 4 16 5 10 6 2 7 1 Total 144 (a) The mean and SD of Y are y = 2.23 and s = 1.47. What percentage of the observations are within (i) 1 SD of the mean? (ii) 2 SDs of the mean? (b) Determine the total number of larvae in all 144 squares. How is this number related to y? (c) Determine the median value of the distribution.
