Use the formula E = t (s/?n) to find the value of E given the values of s, n, and ?. (Hint: The value of

Use the formula E = t (s/?n) to find the value of E given the values of s, n, and ?². (Hint: The value of t is determined from the table in the Written Example using the given value of ?² and the formula d.f. = n - 1.) Round the result to the nearest ten-thousandth. S= 19.5 ,n = 9, ?²= 0.02E= ___________
