Problem
The mean height of 50 tomato plants in a greenhouse is 35 cm and the standard deviation is 4 cm.
(a) After a week, every plant has grown exactly 6 cm. Calculate the new mean and the new standard deviation.
(b) In the following week, each of these grown plants is trimmed to 80\% of its height obtained in part (a). Determine the mean and standard deviation after trimming.
