i CHOSE B

IS THIS CORRECT?

To find the mean final exam score, you need to add up all the scores and divide the sum by the number of scores. In this case, there are 15 scores.

Sum of all scores = 193 + 185 + 163 + 186 + 192 + 135 + 158 + 174 + 188 + 172 + 168 + 183 + 195 + 165 + 183 = 2722

Mean final exam score = Sum of all scores / Number of scores = 2722 / 15 = 181.47

So, the mean final exam score is approximately 181.47, which is not one of the given options (A) 183, B) 185, C) 176) in this case.

To find the median final exam score, you need to arrange the scores in ascending order and find the middle value. In this case, the scores arranged in ascending order are:

135, 158, 163, 165, 168, 172, 183, 183, 185, 186, 188, 192, 193, 195

Since there are 15 scores, the middle value is the 8th score, which is 183. Therefore, the median final exam score is 183, which matches option B) in this case.

So, your answer for the median final exam score is correct with option B) 183. However, your answer for the mean final exam score is incorrect as it is not one of the given options.
