The correct option is : no mode
<u><em>Explanation</em></u>
The given data set is:
The <u>mode is the number that is repeated more often</u> than any other number in the data set.
But here we can see that all the numbers in this data set are different. That means <u>they appear only once</u>.
So, there will be 'no mode' in this set.
Answer:
6
Step-by-step explanation:
The mean of a list of test scores is 80
Adding an additional test score of 92 caused the mean to rise to 82
To find:
After this additional, how many total test are in the list ?
Solution:
Let the total number of test at first =
And sum of total score =
As we know, mean =
Multiplying both sides by
Now, as adding an additional test score of 92 caused the mean to rise to 82,
By dividing both sides by minus ( - )
By dividing both sides by 2
Thus, total number of test at first = = 5
And, after this additional score added, total number of tests are
