Answer :
Final answer:
The mean of the first set of numbers is 6.4, while the mean, median, and mode of the golf scores are 69.7, 69, and 69 respectively. The closest answer choice provided by the student is c. 69.1, 69, 69.
Explanation:
To find the mean of the first set of numbers (6.3, 5.9, 3.2, 5.9, 10.7), you add them together and then divide by the number of values in the set.
Adding these numbers, we get 6.3 + 5.9 + 3.2 + 5.9 + 10.7 = 32.0. Since there are 5 numbers in this set, you divide 32.0 by 5, which gives us a mean of 6.4 (rounded to one decimal place).
For the golf scores, we need to find the mean, median, and mode.
To find the mean, we add all scores together and divide by the number of scores.
The sum of these scores is 1046, and there are 15 scores, so the mean is 1046 divided by 15, which equals approximately 69.7 (rounded to one decimal place).
The median is the middle number when the scores are listed in order. Since there are 15 scores, the 8th score is the median.
In this case, the median is 69. The mode is the score that appears most often, which is 69 (it appears five times).
Thus, the correct answer is: mean = 69.7 (rounding to one decimal place), median = 69, and mode = 69, which corresponds to option c. 69.1, 69, 69 from the student's choices.
Note that there might be a typo, since the calculated mean is 69.7, which is slightly different from the provided options.
Therefore, the exact correct answer should be 69.7, 69, 69, but since this is not an available option, the closest answer provided by the student is c.
