Chucky grabbed 11 items in the grocery store. Each item had a different price, and the mean was about $4.44. On his way to the register, he added a 12th item: a jug of olive oil for $39.99.
How will adding the jug of olive affect the mean an median?
To approach this problem, we can first find the original sum of the prices of the 11 items:
11 × $4.44 = $48.84
Then, we can find the new sum of prices when we add the 12th item:
$48.84 + $39.99 = $88.83
Therefore, the new mean price will be:
$88.83 ÷ 12 = $7.40
Adding the jug of olive oil, which has a much higher value than the other 11 items, significantly increases the mean price.
To find the median, we need to arrange the 12 prices in order from lowest to highest. Since we know that all 11 initial prices are different, the median will be the sixth price, or the one that is right in the middle. We can assume that the jug of olive oil will be the highest-priced item now, so we can insert it in the 12th position. Now, the prices are:
$1, $2.50, $3, $3.50, $4, $4.50, $5, $5.50, $6, $7, $8, $39.99
The median is still $5.50, because the jug did not mess with the order of the previous values.
In summary, adding the jug of olive oil increased the mean price significantly but did not affect the median price.
So it would be "Both the mean and median will increase, but the median will increase by more than the mean."? Am I right?
No, both the mean and median will increase, but the mean will increase by more than the median.
The original mean was $4.44, and the new mean after adding the jug of olive oil will be $7.40. On the other hand, the original median was some value between $4 and $5, and the new median will be $5.50, an increase of $0.50 only. Therefore, the mean increased by more than the median, so your statement is incorrect.

I'm glad I could help! If you have any other math questions or need further assistance, feel free to ask.
Anya plays one round of her favorite online game every day. One week, she played 7 rounds and scored between 120 and 300 points each round. She calculated the mean and median of those scores.
Then, Anya found out that day she scored 300 points was a special "double points" day, so she actually earned 600 points, not 300.
How will this amount increasing affect the mean and median?
The original mean and median were calculated based on 7 rounds, with scores ranging between 120 and 300 points. To begin with, we can calculate the original mean:
Mean = (sum of scores) / (number of scores)
Mean = [(120 + 121 + ... + 300) / 7]
Mean ≈ 207.14
Next, we can calculate the original median. Since there are seven scores, we can list them in order and find the score that is in the middle:
120, 121, 180, 210, 240, 270, 300
The median score is the fourth score, which is 210.
After finding out that her score on one day was 600 points instead of 300 points, we can adjust the sum of scores accordingly:
New sum of scores = (sum of scores) - 300 + 600
New sum of scores = [(120 + 121 + ... + 300) - 300 + 600]
New sum of scores ≈ 1088.57
Therefore, the new mean score will be:
New mean = (new sum of scores) / (number of scores)
New mean = [1088.57 / 7]
New mean ≈ 155.51
As we can see, the mean score decreased significantly because the original mean was biased towards the high end by the 300 score. Adding the actual 600 score brought down the mean.
Next, we can calculate the new median score. We need to list the scores in order:
120, 121, 180, 210, 240, 270, 600
The median score will still be the fourth score, which is 210. Therefore, the median did not change.
To summarize, the increase in one day's score from 300 to 600 points drastically decreased the mean score but did not affect the median score.
So, it would be "The mean will increase, and the median will stay the same." Am I right?
No, the mean will actually decrease, not increase. The correct statement based on the explanation would be: "The mean will decrease significantly, and the median will stay the same."
So it will be "The mean will increase, and the median wil decrease
No, that would be incorrect. The mean will actually decrease, and the median will stay the same.
Adding the actual score of 600 points brought the mean down since the original mean was already biased towards the high end by the 300 score. On the other hand, the median score did not change at all because it only depends on the values of the middle score(s), and the rank of the 300-point score stayed the same when it became 600, so it did not alter the middle values at all.
So which one is itt?
A. Both the mean and median will increase.
B. The mean will stay the same, and the median will increase.
C. The mean will increase, and the median will decrease.
D. The mean will increase, and the median will stay the same.
The mean will increase, and the median will stay the same.
No, that would actually be incorrect. The mean will actually decrease, not increase. The correct statement would be:
The mean will decrease significantly, and the median will stay the same.
You mean "The mean will increase, and the median will stay the same?" (It's correct)
No, sorry for the confusion. I mean that the correct statement is:
The mean will decrease significantly, and the median will stay the same.
