Questions: Classes Frequency 50-57 3 58-65 5 60-73 4 74-81 3 82 - 89 25 5 15

Solution Steps

• The table provides the relative frequencies for each class.
• To find the actual frequencies, multiply the relative frequency by the total number of observations.
• Assume the total number of observations is 20 (since the relative frequencies sum to 1).

| Classes | Relative Frequency | Frequency | |---------|--------------------|-----------| | 50 - 57 | 0.15 | 3 | | 58 - 65 | 0.25 | 5 | | 66 - 73 | 0.20 | 4 | | 74 - 81 | 0.15 | 3 | | 82 - 89 | 0.25 | 5 |

• Sum the frequencies to ensure they match the total number of observations.
• \(3 + 5 + 4 + 3 + 5 = 20\), which matches the assumed total.

• Compare the calculated frequencies with the histograms provided.
• The correct histogram should have bars corresponding to the frequencies: 3, 5, 4, 3, and 5.
