85 hospitals at a moment during the day gives a mean noise level of 46 db. assume that the standard deviation of noise level is really 10 db. part one. assuming that the average noise level of hospitals is what it's supposed to be, what is the probability of a sample of 85 hospitals producing an average as high as your sample (p-value)

V = π × r² × h

The radius of the base is equal to half of its diameter. So, we have:

V = 3,14 × 6,5² × 11
V ≈ 1459.3 cm³
