An illustration shows two sets of dot plots. One is titled Weight in Pounds, Cats and the other is Weight in Pounds, Small Dogs. The plots are shown as an abacus-like representation with dots in a vertical row over each number on a number line. For Cats, a number line with arrows on both ends ranges from 9 to 13 in increments of 1. There is 1 dot above 9, 2 dots above 10, 4 dots above 11, 2 dots above 12, and one dot above 13. For Small Dogs, a number line with arrows on both ends ranges from 8 to 15 in increments of 1. There is 1 dot above 8, 2 dots above 9, 4 dots above 10, 2 dots above 11, 2 dots above 12, 2 dots above 13, 1 dot above 14, and 1 dot above 15.
The dot plots show the weights of randomly selected cats and small dogs in different households. Based on an informal assessment of the visual overlap of these distributions, which animal has the least variability in their weights? Why?
A. Cats, because the range of their weights is greater than that of small dogs.
B. Small dogs, because the range of their weights is less than that of cats.
C. Small dogs, because the range of their weights is greater than that of cats.
D. Cats, because the range of their weights is less than that of small dogs.
C. 3 pounds
D. Cats, because the range of their weights is less than that of small dogs.

The dot plots show the weights of randomly selected cats and small dogs in different households. What is the difference between the modal weights of cats and small dogs?
A.1 pound
B.0.13 pounds
C.3 pounds
D.The modal weights are the same for cats and small dogs.
You didn't compare modal weights
I apologize for the mistake. The correct answer is D. The modal weights are the same for cats and small dogs.
How do you find the modal weight in a set of data numbers
To find the modal weight in a set of numerical data, you need to identify which number occurs most frequently. In other words, the mode is the value that appears most often in the set. Here are the steps to follow:
1. Arrange the data values in ascending or descending order.
2. Count the frequency of the unique values in the data set.
3. Identify the value that occurs most frequently.
If there is more than one value with the same highest frequency, then the data set has multiple modes. If there is no value that occurs more than once, then the data set has no mode.
Two fertilizers are applied to randomly selected potato plants. After several weeks, the potatoes are weighed. The weights in kilograms are as follows. Which fertilizer is generally more effective?
Fertilizer A: 27, 20, 16, 18, 22, 19, 23, 21, 17, 19
Fertilizer B: 28, 19, 18, 21, 24, 20, 25, 27, 29, 21
A. Fertilizers A and B are both ineffective, because there is no difference in the ranges of the weights of the potatoes.
B. Fertilizer A is generally more effective, because the mean and median weights of the potatoes treated with it are higher.
C. Fertilizers A and B are equally effective, because the ranges of the weights of the potatoes are the same.
D. Fertilizer B is generally more effective, because the mean and median weights of the potatoes that were treated with it are higher.
D. Fertilizer B is generally more effective, because the mean and median weights of the potatoes that were treated with it are higher.
Fertilizer A's mean is 20.2 median 19.5 and range is 11
Fertilizers B mean is 23.2 median is 22.5 and the range is 11
Which fertilizer is generally more effective, which statement is true?
A. Fertilizers A and B are both ineffective, because there is no difference in the ranges of the weights of the potatoes.
B. Fertilizer A is generally more effective, because the mean and median weights of the potatoes treated with it are higher.
C. Fertilizers A and B are equally effective, because the ranges of the weights of the potatoes are the same.
D. Fertilizer B is generally more effective, because the mean and median weights of the potatoes that were treated with it are higher.
