1. A sample of size n=49 is drawn from a population whose standard deviation is .
(a) Find the margin of error for a 95%confidence interval for .
b) If the sample size were n=60, would the margin of error be larger would be larger or smaller.
2. Determine the point estimate of the population mean and margin of error for the confidence interval. The lower bound is 23; the upper bound is 27. The point estimate of the population mean is? The margin of error for the confidence interval is?
