Use the formula E = t (s/√n) to find the value of E given the values of s, n, and α². (Hint: The value of t is determined from the table in the Written Example using the given value of α² and the formula d.f. = n - 1.) Round the result to the nearest ten-thousandth. S= 19.5 ,n = 9, α²= 0.02 E= ___________
