Question

fill in the blank. 1 point. the frequency table contains information about the pulse rates of students in a class. class frequency 67 - 75 2 76 - 84 2 85 - 93 6 94 - 102 3 103 - 111 8 112 - 120 3. from the choices below, the correct frequency histogram of the data is choice.

Explanation:

Step1: Analyze class - frequency pairs

The class intervals are 67 - 75 (freq = 2), 76 - 84 (freq = 2), 85 - 93 (freq = 6), 94 - 102 (freq = 3), 103 - 111 (freq = 8), 112 - 120 (freq = 3).

Step2: Match with histograms

We check the heights of the bars in each histogram for the corresponding class - interval ranges. In the correct histogram, the bar for 103 - 111 should be the tallest (height = 8), followed by 85 - 93 (height = 6), and the bars for 67 - 75 and 76 - 84 should have the same height (height = 2), and the bars for 94 - 102 and 112 - 120 should have the same height (height = 3).

Answer:

The correct choice is the one that matches the above - described bar heights for each class interval. Without seeing the exact details of each option, based on the frequency values, we know the general shape and relative heights of the bars. If we assume the histograms are labeled correctly with class intervals on the x - axis and frequency on the y - axis, we can identify the correct one by comparing bar heights. If we had to choose from options A, B, C, D, we would pick the one where the bar for 103 - 111 is the tallest, 85 - 93 is the second - tallest, 67 - 75 and 76 - 84 have equal shorter heights, and 94 - 102 and 112 - 120 have equal heights that are shorter than 85 - 93 but taller than 67 - 75/76 - 84.
