How do I solve this on the calc ti84 plus?

Question

x: 0,1,2,3,4,5

p(x):0.269,0.584,0.113,0.029,0.004,0.001

in the probability distribution to the right , the random variable x represents the number of marriages an individual 15 years or older has been involved in . Compute the standard deviation

Answer 1

On the calculator:

Enter your data in L1 and L2 (or any of the lists, really). Make sure that the X values go with their corresponding probabilities.

Then go to STAT, go over one to the right for CALC. Hit enter on 1-Var Stats.

The X values should be your list, and the frequency list should be your probabilities (see below)

STAT > CALC > 1-Var Stats

List: L1

FreqList: L2
