Final answer:
For the given numbers (75, 93, 97, 97, 99), the mean is calculated as 92.2, and the median is identified as 97 since it is the middle number in the ordered set. The correct answer is a) Mean is 92.2, Median is 97.
Step-by-step explanation:
The mean and median are measures of central tendency that give us insight into the distribution of a set of numbers. The mean is calculated by adding all the numbers together and then dividing by the total count of numbers. In your case, (75 + 93 + 97 + 97 + 99) / 5 equals 92.2. The median, on the other hand, is the middle number in an ordered list. Here, the ordered list is 75, 93, 97, 97, 99, so the median is the third number: 97.
Based on the calculations:
- The mean is 92.2.
- The median is 97.
The correct answer is a) Mean is 92.2, Median is 97.
