A sample of 57 healthy human body temperatures yields a sample average of 98.63 degrees F. If the population is known to be normal with a standard deviation of 0.26 degrees F, determine the margin of error of a 95% confidence interval. Round to the nearest thousandth, such as "0.024 degrees F" QUESTION 11 sample size 3: Healthy human body temperatures have a deviation of 0.32 degrees. If a 90% confidence interval is need for the average such temp., with a margin of error of 0.02 degrees, how many data points will be needed for the sample? QUESTION 12 2 po sample size 2: Adult American male heights have a deviation of 4.4 inches. If a 99% confidence interval is need for the average such height, with a margin of error of 0.05 inches, how many data points will be needed for the sample
