The distribution of weight for a sampte of students in group A is shown in the following table. d) Weight (kilograms) Number of students 41 45 2 Mi - 50 7' 23 56 - 60 13 61 - 65 4 66 - m 5 T1 - 75 1 Obtain the mean weight and its standard deviation. (5 marks) Construct a histogram for the above data. (3 marks) From the histogram. estimate the modal value and explain its meaning. (2 marks) Determine the shape of the distribution by using an appropriate calculation. (3 marks) e) The mean and varianoe for weight obtained by group B students is 57.33 and 55.19 respectively. Using the appropriate measurement, compare the performance consistency of the two groups
