Question

Leonard goes to the pumpkin patch and measures the mass of each pumpkin in kg. the distribution of the pumpkins masses is given below. what is the class width?

a) 0.5 kg
b) 1.0 kg
c) 1.5 kg
d) 2.0 kg

Answer 1

The class width is the difference between the upper class limit and the lower class limit of a class interval in a frequency distribution. In this case, the range of the pumpkin masses is divided by the number of classes to determine the class width.

Step-by-step explanation:

The class width is the difference between the upper class limit and the lower class limit of a class interval in a frequency distribution. To find the class width, we need to determine the range of the data and divide it by the number of classes. In this case, the range of the pumpkin masses is the difference between the maximum mass and the minimum mass. The maximum mass is 67 kg and the minimum mass is 1.00 kg. Therefore, the range is 67 - 1.00 = 66. Now, we need to decide on the number of classes. Since the distribution is not provided, we cannot determine the optimal number of classes. However, let's assume that there are 10 classes for simplicity. To find the class width, we divide the range by the number of classes: 66 / 10 = 6.6 kg. Since we are given answer choices in kilograms, we need to round the class width to the nearest whole number, which is 7 kg. Therefore, the answer is d) 2.0 kg.
