Test: Data Handling - Question 5

The mean weight of 100 students in a class is 46 kg. The mean weight of boys is 50 and of girls is 40 kg. Therefore, the number of boys is:

Detailed Solution for Test: Data Handling - Question 5

Let number of boys are x and then number of girls = (100-x).
Thus,

→ x = 60.
Number of boys = 60.

Find the mean weight of the data set shown. 5 kg, 43 kg, 18 kg, 26 kg, 28 kg, 46 kg, 41 kg, 1 kg

Detailed Solution for Test: Data Handling - Question 6

Mean =  Sum of mass weights / Total number of weighs

= (5 + 43 + 18 + 26 + 28 + 46 + 41 + 1)/8

= 26

Test: Data Handling - Question 7

A kennel can accommodate 12 dogs that weigh (in pounds) 6, 14, 23, 17, 19, 27, 39, 7, 33, 4, 11, and 13. Find the range of their weights.
