1)   Construct a grouped frequency distribution table for the following weights (in gm) of 30 oranges using the equal class intervals, one of them is 40-45 (45 not included). The weights are: 31, 41, 46, 33, 44, 51, 56, 63, 71, 71, 62, 63, 54, 53, 51, 43, 36, 38, 54, 56, 66, 71, 74, 75, 46, 47, 59, 60, 61, 63. 2)   Find Mean and Median for the above data.  3) Draw a Histogram for the above data.  4) Draw a frequency polygon to represent the above data.   5) Construct a combined histogram and frequency polygon for the   distribution.​
