a. Assuming that head circumferences for infants are normally distributed with standard deviation 1.6 cm, determine a 90% confidence interval for the mean head circumference of all infants. The confidence interval for the mean head circumference of all infants is from cm to (Round to one decimal place as needed.) b. Obtain the margin of error, E, for the confidence interval you found in part (a). The margin of error is cm. (Round to one decimal place as needed.) cm. c. Explain the meaning of E in this context in terms of the accuracy of the estimate. Choose the correct answer below and fill in the answer box to complete your choice. (Round to one decimal place as needed.) O A. We can be 90% confident that the estimate of μ by x is cm. OB. We can be 90% confident that the error made in estimating u by x is at least cm.
