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)

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
