Question 3.32
The proportion of the budgets for a certain type of industrial company that is allocated to environmental and pollution control is coming under scrutiny. A data collection project determines that the distribution of these proportions is given by:
f (y) = 5 (1-y)^4, 0<=y<=1
0, elsewhere
a) Verify that the above is a valid density
b) What is the probability that a company chosen at random expends less than 10% of its budget on environmental and pollution controls ?
c) What is the probability that a company selected at random spends more than 50% on environmental and pollution control ?
