The weekly repair cost y for a machine has a probability density function given by f(y)={3(1−y)2,0,0≤y≤1otherwise. with measurements in hundreds of dollars. how much money should be budgeted each week for repair costs so that the actual cost will exceed the budgeted amount only 10% of the time? [hint: beta probabilities applet, or use the relationship to the binomial distribution.] 1
