Question

The numbers listed represent the amount of precipitation​ (in inches) last year in six different U.S. cities. Find the standard deviation. Round to two decimal places. 12.2, 11.1,46.2,33.9,24.4,10.6

Answer 1

Let x(i) = values, where i = 1 to sample size,

Compute the mean = (sum of x(i))/sample size

Then compute variance = sum of all (x(i) - mean)^2/(sample size - 1)

Standard deviation equals the square root of the variance

Answer 2

The standard deviation is

so 14.64
