A random sample of size 100 is taken from a normal population with σ = 25. What is the probability that the mean of the sample will differ from the mean of the population by 3 or more either way? 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. If S21 and S22 are the variances of independent random samples of sizes n1 = 10 and n2 = 15 from normal populations with equal variances, find P(S21 / S22 < 4.03). Use the result of part (c) of Exercise 8.58 to find the probability that in a random sample of size n = 10 at least 80 percent of the population will lie between the smallest and largest values. Basing their decisions on optimism (that is, maximizing maximum gains or minimizing minimum losses), what decisions should be reached by (a) The manufacturer of Example 9.1; (b) Ms. Cooper of Exercise 9.12; (c) The truck ...Post your question
