1. Compute PU: - 20

where X has the density 1. Compute 20 < X < + 20) function g(x) elsewhere and compare with the result given in Chebyshev's theorem. 2. Provide one example to each of the following distributions. Please give your explanation and reason why the example belongs to the respective distribution. a. Discrete uniform distribution b. Binomial distribution Multinomial distribution d. Hypergeometric distribution Multivariate hypergeometric distribution f. Geometric distribution g. Negative Binomial distribution. h. Normal distribution 3. Given that the grades of statistics exam are normally distributed with a mean of 70 and a standard deviation of 5. If 10% of the class are given A's, what is the lowest possible A and the highest possible B?
