Since the sample is greater than 10, we can approximate this binomial problem with a normal distribution.
First, calculate the z-score:
z = (x - μ) / σ = (37000 - 36000) / 7000 = 0.143
The probability P(x > 37000$) = 1 - P(<span>x < 37000$),
therefore we need to look up at a normal distribution table in order to find
P(z < 0.143) = 0.55567
And
</span>P(x > 37000$) = 1 - <span>0.55567 = 0.44433
Hence, there is a 44.4% probability that </span><span>the sample mean is greater than $37,000.</span>
Answer:

40 cubic ft of water are needed to completely fill the aquarium. I did it right this time. ;)
9+4+7+3+10+9=42
42÷6= 34.5. I believe "mean" is the same as avgerage.
Answer:B
Step-by-step explanation:
9 : 180 = 1 : 20
5: 200 = 1:40
12:240 = 1 : 20
10 : 400 = 1 : 40
8 : 560 = 1 : 70
