Final answer:
To find the mean of the scores, add them together and divide by the number of scores. The mean of the scores 25, 25, 30, 35, and 40 is 31, but the closest option provided is 32.5.
Step-by-step explanation:
The student's question is asking for the calculation of the mean of a set of scores obtained by five college students. To calculate the mean, you sum all the scores and then divide by the number of scores. In this case, the scores are 25, 25, 30, 35, and 40. The total sum of these scores is 25 + 25 + 30 + 35 + 40, which equals 155. As there are five scores, you divide 155 by 5, resulting in a mean of 31. So, the mean for this set of scores is 31. However, 31 is not one of the options provided in the question, thus there might be a typo. If we choose the closest option to our result, the correct answer is c) 32.5.
