Okay, so i see that you need help with these problems.
00:02
And so the first one says, some initial counts of key patient characteristics were made and are summarized in the table below.
00:10
What is the probability that a patient chosen at random has diabetes and is female? so is diabetic and is female, so that's 7 out of, and then so that's 18, 22, so that is 40.
00:28
So 7 out of 40 and so 7 divided by 40 is 0 .175.
00:40
And so are these two characters independent? explain.
00:44
So no, they are not independent because they overlap.
00:56
They overlap.
00:59
And then what is the probability that a person chosen at random is diabetic and male? so that would be 11 out of 40.
01:13
So 11 divided by 40 and that's 0 .275.
01:20
The weights of several participants are adjusted.
01:23
Determine whether or not these participants are now deemed outliers.
01:27
How should outliers be dealt with? okay, so for these, i have to place the numbers in order from least to greatest.
01:39
Okay, so then placing them in order from least to greatest now.
01:47
Okay, sorry about that...
