Mung Ying and Shintinye have a total of 16 samples that are examined to determine the airborne concentration of acetone in an industrial workplace. The mean concentration was found to be 375 ppm with a standard deviation of 112 ppm. Assuming that airborne concentration is a normally distributed variable, determine the 99% confidence interval for the mean concentration of acetone.

Step 1
947, we can calculate the margin of error using the formula: Margin of error = Critical value * Standard deviation / sqrt(sample size) Margin of error = 2.947 * 112 / sqrt(16) Margin of error = 82.508 Show more…

The concentration of carbon monoxide (CO) in a gas sample is measured by a spectrophotometer and found to be 85 ppm. Through long experience with this instrument, it is believed that its measurements are unbiased and normally distributed, with an uncertainty (standard deviation) of 12 ppm. Find a 95% confidence interval for the concentration of CO in this sample. Round the answer to 3 decimal places.

Find the sample size required to estimate the population mean. Data Set 3 "Body Temperatures" in Appendix B includes 106 body temperatures of adults for Day 2 at 12 ant, and they vary from a low of $96.5^{\circ} \mathrm{F}$ to a high of $99.6^{\circ} \mathrm{F}$. Find the minimum sample size required to estimate the mean body temperature of all adults. Assume that we want $98 \%$ confidence that the sample mean is within 0.1 $^{\circ} \mathrm{F}$ of the population mean. a. Find the sample size using the range rule of thumb to estimate $\sigma$ b. Assume that $\sigma=0.62^{\circ} \mathrm{F},$ based on the value of $s=0.62^{\circ} \mathrm{F}$ for the sample of 106 body temperatures. c. Compare the results from parts (a) and (b). Which result is likely to be better?
