The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 26.5 for a sample of size 565 and a standard deviation of 12.2. Round to two decimals a. What is the Standard Error?
b. Write a confidence interval state for a test at the 90% confidence level.

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !
