2. In a field various plants were grown, find the mode height of the plants from the given frequency distribution. Also calculate the standard deviation of the given data series. Height of plants (in inches) 1-5 6-10 11-15 16-20 21-25 No. of plants 7 10 16 32 24 6+6=12 UNIT- II 3. a. Calculate the Karl Pearson coefficient of correlation of the plant growth of two species A and B from the given data series. Interpret the result accordingly. Species A (in inches) 10 6 9 10 12 13 11 9 Species B (in inches) 9 4 6 9 11 13 8 4 b. A basket contains 5 white and 8 red flowers. Two drawing of three flowers are made. Find the probability that the first drawing will give 3 white and the second drawing with 3 red flowers. (i) the flowers are replaced before the second trial and (ii) the flowers are not replaced before the second trial. 6+6=12
