Data is the most common use software in economics and i'm going to start answering your question with the command so you can reply, replicate it.
00:14
So the first question is how many women in the sample in the sample are in total 1 ,38 women.
00:20
A homer report to smoking during pregnancy would be this difference, so you can do display 176 and that's the amount of women that, that's being in a different.
00:32
Smoke and you just subtracted.
00:35
So, 212 women for smoking during pregnancy.
00:38
What is the average number of cigarettes smoke during pregnancy? you just applied someone cigarettes and you can see that is two cigarettes during pregnancy.
00:48
What is the average a good measure of the typical woman in this case? no, because as we saw there are a lot of zero cases so that will pull a lot and for example wouldn't allow to see that there are some cases that these have that have this higher value so it's better to use other values such as the mean.
01:07
The third question is among women who's monitoring pregnancy what is the average number cigarettes per day so you could use in this case mean six six is different from zero and you will see that the mean is so higher so that could give a better understanding of the value and also it's better so you can compare it and as you can see the value go up from 2 to 13 and give a better representation...
