In a study on infants, one of the characteristics measured was head circumference. The mean head circumference of 14 infants was 34.6 cm. Assuming that head circumferences for infants are normally distributed with standard deviation 2.1 cm, determine a 95% confidence interval for the mean head circumference of all infants. Step 1: Determine ??/2. Step 2: Determine the CI. Step 3: Interpret the CI. Obtain the margin of error, ?, for the CI you found in part (a). Determine the...
