Hello, so from the given data, let us first find the mean in standard division, and then we can make our conclusions.
00:13
So the mean is going to be np, which is 200 times 0 .12, and that is 24.
00:32
And the standard division is going to be square root of np into 1 minus p.
00:47
You already know what mp is, 24.
00:56
And then 1 minus 1 2.
01:05
That's 0 .88.
01:12
24.
01:16
There we got square root on that answer.
01:24
Standard division is 4 .60.
01:38
So you have a mean of 24 and a standard division of 4 .6.

Have been told that he made only 10 sales.
01:54
So given that he made only 10 sales.
02:09
Let's look at the implication of that...
