Question

helllp Use the relative frequency table shown to the right to calculate the number of the 600 measurements falling into each of the measurement classes. Then graph a frequency histogram for these data. -Measurement Class 0.5-2.5 2.5-4.5 4.5-6.5 6.5-8.5 8.5-10.5 10.5-12.5 12.5-14.5 14.5-16.5 Relative Frequency 0.15 0.05 0.10 0.05 0.20 0.15 0.25 0.05 Calculate the number of measurements that fall into each class. Measurement Class Frequenc 0.5-2.5 2.5-4.5 4.5-6.5 6.5-8.5 8.5-10.5 10.5-12.5 12.5-14.5 14.5-16.5

Explanation / Answer

To get the frequencies themselves, we simply multiply the relative frequencies by the sample size, n = 600.

Thus,

Plotting these, we see that the correct graph is OPTION B. [CORRECT GRAPH, OPTION B]

Relative Frequency Frequency 0.15 90 0.05 30 0.1 60 0.05 30 0.2 120 0.15 90 0.25 150 0.05 30
