# Question: Use the result of Exercise 8 54 and that of part

Use the result of Exercise 8.54 and that of part (a) of Exercise 8.52 to find the sampling distribution of R for random samples of size n from an exponential population.

## Answer to relevant Questions

Use the result of Exercise 8.54 to find the sampling distribution of R for random samples of size n from the continuous uniform population of Exercise 8.46. How many different samples of size n = 3 can be drawn from a finite population of size (a) N = 12; (b) N = 20; (c) N = 50? Rework part (b) of Exercise 8.66, assuming that the population is not infinite but finite and of size N = 400. Integrate the appropriate chi-square density to find the probability that the variance of a random sample of size 5 from a normal population with σ2 = 25 will fall between 20 and 30. Use a computer program to verify the five values of f0.05 in Table VI corresponding to 7 and 6 to 10 degrees of freedom.Post your question
