The true statement about the number of correct answers is that the: A. median = mode.
Mathematically, the mean for the number of correct answers can be calculated by using the following formula:
Mean = [F(x)]/n
Total frequency, n = 3 + 4 + 6 + 9 + 8 = 30.
F(x) = [(1 × 3) + (2 × 4) + (3 × 6) + (4 × 9) + (5 × 8)] = 105.
Mean = 105/30
Mean = 3.5.
For the median, we have:
The median for the number of correct answers is the average of the 15th and 16th number:
Median = (4 + 4)/2
Median = 8/2
Median = 4.
For the mode, we have:
The mode for the number of correct answers is the answer with the highest frequency, which is 4 with a frequency of 9.
Therefore, the true statement about the number of correct answers is that the median is equal to mode.
