Answer:
B. 95% confident the average concentration of PCBs in the water supply is between 2.9 ppb and 3.5 ppb
Step-by-step explanation:
You are given the total number of samples, the concentration of lead, and the standard deviation. The standard deviation represents how inaccurate the estimation of the concentration of lead in the drinking water. This means that there can only possibly be a 0.3 ppb error in the estimation. 3.2-0.3=2.9, and 3.2+0.3=3.5

Answer:
17ft
Step-by-step explanation:
What you're going to do is solve this backwards so to find volume the eqation is v=(pir^2)h, so what you're going to do is:
833pi=(pi7^2)h you cross out pi and square 7 833=49*h then you divide 49 from both sides and get 17
