Brewed decaffeinated coffee contains some caffeine. We want to estimațe the amount of caffeine in8 ounce cups of decaf coffee at local fast food restaurants. For this question, assume that thestandard deviation in the amount of caffeine in 8 ounces of decaf coffee is not known and isestimated to be 2.3 mg using the samplestandard deviation. This time we took a sample of n =9 eight-ounce cups of coffee from fast food restaurants on Robert Street in West St. Paul. Thesample mean amount of caffeine turned out to be 9 mg.Construct a 99% confidence interval estimate for the true mean amount of caffeine in eight-ouncecups of decaf coffee, using the new information described above. Type the formula for yourconfidence interval into the text box first and then type a second version where you fill in all of thenumbers in your formula. You don't have to calculate the final numeric result.

Mean = 9 Standard deviation = 2.3 Sample size = 9 significance level = 0.01 df = n-1 = 9 - 1 = 8…

It takes an average of 9.1 minutes for blood to begin clotting after an injury. An EMT wants to see if the average will decline if the patient is immediately told the truth about the injury. The EMT randomly selected 49 injured patients to immediately tell the truth about the injury and noticed that they averaged 8 minutes for their blood to begin clotting after their injury. Their standard deviation was 3.31 minutes. What can be concluded at the the a = 0.05 level of significance? a. For this study, we should use Select an answer b.
