A histogram would be the best choice for summarizing the frequency of infants falling into different intervals of weight. A histogram displays continuous data by dividing the range of values into intervals, called bins, and counting the number of observations that fall into each bin. In this case, the weight of newborn infants is a continuous variable, and a histogram can show the distribution of weights and the frequency of infants falling into different weight intervals. A bar chart is a good choice for summarizing categorical data, but it wouldn't be suitable for this scenario. A scatterplot is used to display the relationship between two continuous variables, so it wouldn't be appropriate.
