On an easy test, the mean score was 96 out of a possible 100 points. the distribution of the test scores is likely to bea) diagonally skewed .b) symmetric. c) negatively skewed d) positively skewed.

Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Mean score = 96

Sample size = 100

We need to find the distribution of the test scores is likely to be :

In negatively skewed, the mean is to the right side.

It also shows that the tail on the left side is longer than the tail on the right side.

And the bulk value lies in the right of the mean.

In our situation, mean is to the right side and tail is to the left side.

Hence, it is negatively skewed.

Therefore, Option 'C' is correct.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
