Question

A class marks of each interval. 5. The weights in grams of 50 apples picked at random from a consignment are as follows: 106, 107, 76, 82, 109, 107, 115, 93, 187, 195, 123, 125, 111, 92, 86, 70, 126, 68, 130, 129, 139, 119, 115, 128, 100, 186, 84, 99, 113, 204, 111, 141, 136, 123, 90, 115, 98, 110, 78, 90, 107, 81, 131, 75, 84, 104, 110, 80, 118, 82. Form the grouped frequency table by dividing the variable range into intervals of equal width, each corresponding to 70 gms in such a way that the mid-value of the first class corresponds to 70 gm.​
