(S 9.2) Recall that a confidence interval for the sample mean can be calculated using the interval x¯?tn?1?sn??????x¯+tn?1?sn??? Thus, the margin of error is tn?1?sn??? We can recover the margin of error from an interval constructed on the calculator using algebra. Suppose a random sample of size 16 was taken from a normally distributed population, and the sample standard deviation was calculated to be s = 6.3. We'll assume the sample mean is 10 for convenience. a) Calculate the margin...
