Q2. The diameter of holes drilled in a part is denoted by a random variable x. It has been observed that the drilling process resulted in hole diameters larger than the target value of 12.5 millimeters. The distribution of x can have modeled by a probability density function in the form of f(x) = 20 exp(-a (x-12.5)) x2 12.5 (10 Pts.) (a) Find a (b) If a part with a diameter larger than 12.60 millimeters is scrapped, what proportion of the part is between 12.5 and 12.6 millimeters?
