10-Identify the best point estimate to use when estimating a population proportion.

Use the information described in Question 11 to answer questions 11 through 16.

Note that the parameters given in Question 11 are subject to randomization and may result in different numeric results on subsequent attempts.

All calculations must be accurate to the nearest thousandth place and include any leading

zeros.

11-A random sample of 40 full-term female babies in the United States found that 20% were born weighing less than 5.5 lbs. Work through the following questions to create and interpret a 99% confidence interval for the population proportion of full-term female babies born in the United States that weigh less than 5.5 lbs.

Calculate the critical value to be used for this confidence interval and explain how this value was found.

12-Calculate the margin of error to be used for this confidence interval.

13-Describe the formula used to calculate the margin of error in terms of the variable inputs. Identify what each variable represents.

14-Calculate the upper and lower limits of the confidence interval. Clearly label each result.

15-Describe the formulas used for calculating the upper and lower limits of the confidence interval in terms of the variable inputs. Identify what each variable represents.

16-Interpret the confidence interval in the context of the scenario.
