Round your answer to 5 decimal places. I 3. Find the margin of error for the condence interval. Round your answer to 1 decimal place. I 4. Construct the condence interval for birth weights. Enter your answer as an open interval of the form [(1.1)] and round to the nearest integer. 5. Babies weighing less than 2500 grams are considered to be of low birth weight. Can you conclude that the average birth weight is greater than ESDD grams? 0 No conclusions can be drawn since the condence interval contains 25m]. 0 No. the entire confidence interval is below 25m). 0 lies, the entire condence is above 25m]. You want to obtain a sample to estimate a population mean. Elased on previous evidence. you believe the population standard deviation is approximately or = 49.5. You would lil-ce to be 99.5% condent that your esimate is within 4.5 of the true population mean. How large of a sample size is required? Do not round mid-calculation. However. use a critical 2 value aocurate to two {2] decimal places.
