Correct option is B
The correct option is (b)
1. Mean:
Add all the values and divide by the number of observations.
Sum = 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9 + 9 + 10 + 10 + 11 + 11 + 12 + 13 = 134
Number of observations = 15
Mean = 134 / 15 = 8.93
2. Median:
Since the data is already arranged in ascending order, the median is the middle value. For 15 values, median is the 8th value.
The 8th value = 9
Median = 9
3. Mode:
Mode is the value that appears most frequently.
Here, 8 appears 3 times, more than any other number.
Mode = 8
Hence, the correct set is in option (b) Mean = 8.93, Median = 9, and Mode = 8.
