00:13
And it looks like all of our answers are correct except for our last statement because the most common salary would be the mode, the one that's most frequent, which is 45.
00:21
The salary that half the employees salary surpass is the median, which would be 510.
00:26
That's correct.
00:27
The first and third quartiles break our values to the top 25 and lower 25 percent.
00:32
So the percent of employees that surpass 565 at the third quartile is 25 percent.
00:37
And the same thing for our next question when they ask the percentage of the employees that are less than 450, that's the first quartile.
00:43
So that would be 25 percent.
00:45
And we've answered the 16 percent correctly for the percent of employee salaries that surpass 687 because 687 was at the 84th percentile.
