00:01 All right, in this question, we have a sample taken of 10 salaries from employees of a large company.

00:06 And we're told that everybody is going to get a $3 ,000 raise.

00:13 Okay, so that means this person is now going to make $31 ,000.

00:18 This person's going to make $37.

00:23 This person, 44.

00:27 This person, 45.

00:32 This person, 48.

00:38 This person also 48.

00:40 This person 55, then 64, then 75, and then 80.

01:00 Okay, so let's start by, the first question wants to know the mean salary.

01:05 It's going to increase.

01:07 I'm guessing it's asking for the actual value, so let's go ahead and find that.

01:11 You just add all these up together, plus 45, plus 48, plus 48, plus 55, plus 64, plus 75, plus 80 and then you divide by 10.

01:27 So we get 57 .2.

01:33 The median is also going to increase.

01:38 You can find the median just by taking out smallest value, largest, smallest, largest, smallest, largest until we get to the center, smallest, largest.

01:49 And there's the center.

01:51 Since we have two values, we take the average of them, but they're the same number.

01:54 So it's going to be 48...
