Find the margin of error (M.O.E.) that corresponds to a sample of size 6 with a mean of 20.6 and a standard deviation of 5.7 at a confidence level of 99%. Report MOE accurate to one decimal place. M.O.E. = Submit Question 0 Question 3 B 0/2 pts '0 4 6) Details The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 45 for a sample of size 30 and standard deviation 12. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 99% confidence level). Give your answers to one decimal place and provide the point estimate with its margin of error. :I: Submit Question 0 Question 4 E 0/2 pts '0 4 (D Details The effectiveness of a blood-pressure drug is being investigated.
