Solution Steps

Step 1: Count the Frequency of Each Pulse Rate

The pulse rates recorded for the group of 15 students are: \[ 82, 84, 70, 72, 75, 68, 86, 75, 74, 69, 74, 79, 81, 90, 76 \] Counting the occurrences of each value, we find the following frequencies: \[ \text{Frequency} = \{75: 2, 74: 2, 82: 1, 84: 1, 70: 1, 72: 1, 68: 1, 86: 1, 69: 1, 79: 1, 81: 1, 90: 1, 76: 1\} \]

Step 2: Identify the Maximum Frequency

The maximum frequency of occurrences is: \[ \text{max frequency} = 2 \]

Step 3: Determine the Mode(s)

The pulse rates that occur with the maximum frequency are: \[ \text{Modes} = \{75, 74\} \]

Final Answer

The mode(s) is/are \( \boxed{75, 74} \).
