Explanation:
A frequency table contains information on how many times values in different inteverals occur in a data set. To find the frequency for those intervals, we can lay out the values that lie within it. For this frequency table:
5 ≤ h < 10: {5, 6, 6, 7, 8}, Frequency: 5
10≤ h < 15: {10, 10, 11, 12, 12, 12, 13, 14}, Frequency: 8
15 ≤ h < 20: {15, 15, 16, 17, 17, 18}, Frequency: 6
20 ≤ h < 25: {20}, Frequency: 1
