Final Answer:
The most frequent weight in the dot plot representing the weights of 2020 newborns is 3.75 kg (Option B).
Step-by-step explanation:
To determine the most frequent weight from the dot plot, identify the category with the highest frequency. In this case, inspect the weights represented on the plot and observe the category with the greatest number of dots. If the dot plot intervals are given in kilograms, the option with the highest dot count in the corresponding category is the most frequent weight. Calculate the frequencies associated with each weight category to confirm the result (Option B).
For example, if the dot plot intervals are in 0.25 kg increments, the category corresponding to 3.75 kg might have the most dots. Counting the dots within each category reveals the frequency distribution. The category with the highest count represents the most frequent weight. This analysis ensures a precise determination of the most common weight among the newborns.
In conclusion, the dot plot serves as a visual representation of the weight distribution among newborns in 2020. Analyzing the plot allows for the identification of the most frequent weight category by observing the highest dot count. This method provides an insightful summary of the distribution and helps in drawing conclusions about the typical weight range for the newborns in the given dataset.
