**MathGuru**, Monday, March 18, 2013 at 8:08pmUse a formula to find sample size.

Here is one:

n = [(z-value * sd)/E]^2

...where n = sample size, z-value = 1.96 for 95% confidence, sd = 0.26, E = 0.15, ^2 means squared, and * means to multiply.

Plug the values into the formula and finish the calculation. Round your answer to the next highest whole number.
