Question

Construct a histogram for the 7-months weights(kg) of 100 calves.

Answer 1

To construct a histogram for the 7-month weights of 100 calves, we first need to determine the weight distribution and then group the weights into bins.

Let's say the weights of the 100 calves are as follows:
- 45kg, 47kg, 50kg, 46kg, 48kg, 49kg, 52kg, 48kg, 51kg, 53kg, 55kg, 54kg, 49kg, 50kg, 48kg, 47kg, 46kg, 45kg, 49kg, 51kg, 52kg, 50kg, 48kg, 47kg, 46kg, 53kg, 56kg, 54kg, 52kg, 51kg, 50kg, 49kg, 48kg, 47kg, 46kg, 45kg, 50kg, 53kg, 55kg, 52kg, 51kg, 49kg, 48kg, 46kg, 47kg, 44kg, 46kg, 49kg, 52kg, 51kg, 50kg, 48kg, 47kg, 46kg, 53kg, 55kg, 54kg, 52kg, 51kg, 50kg, 49kg, 48kg, 47kg, 46kg, 45kg, 51kg, 53kg, 55kg, 52kg, 51kg, 50kg, 49kg, 48kg, 47kg, 46kg, 44kg, 46kg, 49kg, 52kg, 51kg, 50kg, 48kg, 47kg, 46kg, 53kg, 55kg, 54kg, 52kg, 51kg, 49kg, 48kg, 46kg, 47kg, 46kg, 45kg

Now, let's group these weights into bins:
- 40-44kg: 3 calves
- 45-49kg: 31 calves
- 50-54kg: 52 calves
- 55-59kg: 14 calves

Finally, we can construct the histogram using these bins and frequencies:

Frequency
| x | x | x |
| x | x | x |x
| x | x | x |x
| x | x | x |x
| x | x | x |x
-------------------------------
40-44 45-49 50-54 55-59
Weight (kg)

This histogram visually represents the distribution of weights for the 7-month-old calves.
