Question: 12 people in a family are having their picture taken,how many combinations are there? most formulas don't include 1 person 2 people ,3 person combo's etc. subject A and B are one combo but B and A would not count.
I have another comment on the placement of Z in the pdf formula. Z = (x-mean)/std dev. So I guess the Z should appear in the numerator of the exponential value.
for the most part this was correct but calling that graph slightly positively skewed is wrong it would be negatively skewed because the longer tail goes to the left
q dijo?
jaja

Oh god. All that work is one line of R code. plot(dnorm()). Seriously, drop Excel like the bitch it is and use a language like R or MATLAB.

@danish234 yes, i think I did. My bad, the plot charts the formula so i didn't notice. Nice catch

Fantastic presentation.

Cut the loud and unnecessary music and it's a fine example.

nope: skew for this dataset is postive: + 0.76

I may be wrong, but it appears to me that the tallest value >0, which means pos. So he is correct.
