Question

A researcher is interested in the toxicity of cigarette smoking in humans. One variable measure that he decides to investigate involves measuring the pH of the urine from smokers to see if there is an increase in toxicity. In order to carry out a statistical test, the researcher collects a SRS of 61 current smokers from a population with a known standard deviation of 0.8. A) If the researcher wants to be 95% confident about his estimate, calculate the margin of error based on the above information. B) Carry out the same calculation above, but assuming the researcher wishes to be “virtually certain” about his estimate. (Use Z=3.0) C) Compare the margin of errors calculated above.
