Answer:
- B) 41 − 45; 46 − 50; 51 − 55; 56 − 60
Step-by-step explanation:
When you build a histogram the intervals must be of the same size. About 4 to 8 intervals is good but it also depends on the number of data and the range of those data.
Option D has only two intervals. That is too few. Thus, this is discarded. Three intervals also seems few. Thus, option C, is not good.
The option A shows intervals of different size:
- 46 - 41 = 4
- 49 - 46 = 3
- 52 - 49 = 3
- 56 - 53 = 3
Thus, this is not good either.
The optio B seems good:
Interval Frequency
- 45 - 41 = 4 3
- 50 - 46 = 4 4
- 55 - 51 = 4 4
- 60 - 56 = 4 1
Hence, the correct answer is B) 41 − 45; 46 − 50; 51 − 55; 56 − 60
