Document Summary
Calculate the observed cumulative probabilities (in %) for each data (present your answer in a table). j. Name: student #: (20%) let x denote the number of impurities in a 1 inch length of titanium wire. The probability mass function of x is presented in the following table. x. One hundred (100) wires are sampled from this population. What is the probability that the average number of impurities per wire in this sample is less than 0. 5? (hint: calculate the mean and the variance and assume that the central limit theorem can be used). 0 y x i yx i y. _< 0 x: (15%) a new plastic mix is being evaluated.
