Changes were made to tighten the quality control requirements. Following these changes, 20 months passed before the first complaint. Does it appear as if the quality tightening was effective? Assigned Muhamma Note: 10 points 1. The continuous random variable X has a gamma distribution, with parameters a and B, if its probability density ate function is given by fx (x) = Barajx-le-*/B x>0 otherwise where the gamma function is defined by r(a) = x-ledx, for a > 0. Class com 2. You are not allowed to use computer to solve the integral. You can use the table of the Incomplete Gamma Function though. If you do so, you have to attach the table with your solution and indicate the values read from it. ment.. 3. If you want to validate your solution with a statistical software like R, or some Python/Julia libarary, you may do so, but it carries no additional credit. You can attach the code file to your submission as well. O Type here to search Y 8:17 AM 12/12/2020
