answer all question with detailed explanation

During the packaging process at panel displays are known to get scratched. Assume that the number of scratches on a at panel display follows a Poisson distribution. A random sample of 100 flat panels had a total of 11 scratches. (a) Develop a procedure for testing the hypothesis that the mean number of scratches per at panel is Au. (b) Use the procedure you developed to test the hypothesis that the mean number of scratches per at panel is 0.136, at 95% condence level. (c) What is the \"prvalue of the sample? ((1) Given the sample, nd the 95% condence interval for the mean number of scratches per flat panel
