Where

is the mean value, z is the associated z value, s is the standard deviation and n is the number of samples.
We know that standard deviation is simply a square root of variance:

The confidence interval of 95% has associated z value of <span>1.960.

The fraction of winter Olympics that hasn't been held in the U. S is 9/11
3 radical 70. 9 times 70 is 630, 9 squared is 3.
