1. Assume the room rate for a 3-star hotel in Paris follows a normal distribution with a mean of 175€ and a standard deviation of 16€. What is the probability that a randomly selected 3-star hotel has a room rate of Z(X) = (x-μ)/σ σ=16 μ=175 a) Less than 195 Euros? Z (195) = (195-175)/16 = 1‚ 25 so 89‚ 4% b) More than 180 Euros? Z (180) = (180-175)/16 = 0‚ 31 so 62‚ 2% c) Exactly 170 Euros? Z (170) = (170-175)/16 = - 0‚ 31 so 37‚ 8% d) Between 150 and 182 Euros?
