Values are uniformly distributed between 185 and 261. "(Round your answers to 3 decimal places, e.g. 0.253.) "(Round your answer to 1 decimal place, e.g. 1.2.) (a) What is the value of f(x) for this distribution? (b) Determine the mean of this distribution: (c) Determine the standard deviation of this distribution: (d) Probability of (x>250)= (e) Probability of (194x236)= (f) Probability of (x211)=
