A random sample of 48 female professional soccer players found an average height of 67 inches, with a standard deviation of 2.2 inches. Build a 93% CI for the mean height of female professional soccer players This will be a T-Interval since o is not known. So we need to compute the Degrees of Freedom: d. f. = n - 1 a. d. f. To find the Margin of Error, E, we need to find the Critical Value, T.. To do this we use invT(C + (1- C)/2,d.f.), where in this problem C = 0.93. Round to three decimals. b. Te = Round to one decimal. Next we find the Margin of Error: E = Tc. c. E = Finally, we compute our Cl: – E <µ < ã + E
