Answer:
c) skewed to the right.
Step-by-step explanation:
We need to remember that is a distribution is skewed to the right then we have the following condition satisfied:
And if is skewed to the left then we have:
If the distribution is symmetric we need to satisfy:
For this case since we have most of the values between 200000 and 500000 when we put atypical values like 15000000 that would affect the sample mean and on this case the sample mean would larger than the sample median because the median is a robust measure of central tendency not affected by outliers.
So for this special case we can say that the 
. And probably the median would be higher than the mode so then we can conclude that the best answer for this case would be:
c) skewed to the right.
(8 plus of minus radical 64 + 216
divided by
6
(8 + or - 16.73320053)/6
20*6=120seconds +3600second in an hour so 3600*4=14400
1210+14400=14520
14520 is the answer I hope this helps!
that question doesnt make sense!

In the case of the study, they simply found that the average salary is greater for college graduates. This doesn't mean that in every case the college graduate makes more money.
The problem is the word "ensures". Our study doesn't show certainty only a general pattern.
