Maybe.. B or D
i think its D
I know it D
thanks for the ancer its D
Well, well, well, let me juggle these numbers for you. Looking at Jen's scores first, we see that she got a 45, 91, 84, 66, and 74. Now let's take a peek at Ron's scores: 70, 95, 99, 69, and 72.
To compare their test scores, we can calculate the median and mean for each of them.
The median of Jen's scores is 74, while the median of Ron's scores is 72.
So, according to the medians, option A doesn't fly because the median of Jen's scores is not greater than the median of Ron's scores. Sorry, option A!
Now, let's do some mean calculations. The mean of Jen's scores is 72, while the mean of Ron's scores is 81.2.
Oh, look at that! Option B doesn't hold up because the mean of Jen's scores is not greater than the mean of Ron's scores. Sorry, option B!
Alrighty then, let's check option C - the mean of Jen's scores compared to the median of Ron's scores. Well, the mean of Jen's scores is 72, and the median of Ron's scores is 72. Considering that they're the same, option C doesn't hold water. Sorry, option C!
Finally, we have option D - the median of Jen's scores compared to the mean of Ron's scores. Hmm, the median of Jen's scores is 74, and the mean of Ron's scores is 81.2. So, option D is the winner! The median of Jen's scores is indeed greater than the mean of Ron's scores.
Congratulations, option D! You are the clown of the day!
To compare the students' test scores, we need to calculate the median and mean for both Jen and Ron's scores.
First, let's calculate the median. The median is the middle value when the data is arranged in order.
Jen's scores in order: 45, 66, 74, 84, 91
Ron's scores in order: 69, 70, 72, 95, 99
Jen's median score is 74.
Ron's median score is 72.
Next, let's calculate the mean. The mean is the average of all the scores.
Jen's mean score:
(45 + 91 + 84 + 66 + 74) / 5 = 360 / 5 = 72
Ron's mean score:
(70 + 95 + 99 + 69 + 72) / 5 = 405 / 5 = 81
Now we can compare the results and determine the correct statement:
A. The median of Jen's scores is greater than the median of Ron's scores.
False. Jen's median is 74, while Ron's median is 72.
B. The mean of Jen's scores is greater than the mean of Ron's scores.
False. Jen's mean is 72, while Ron's mean is 81.
C. The mean of Jen's scores is greater than the median of Ron's scores.
False. Jen's mean (72) is not greater than Ron's median (72).
D. The median of Jen's scores is greater than the mean of Ron's scores.
True. Jen's median (74) is greater than Ron's mean (81).
Therefore, the correct statement is D. The median of Jen's scores is greater than the mean of Ron's scores.
