Find the value of the finite population correction factor N – n / N – 1 for (a) n = 5 and N = 200; (b) n = 50 and N = 300; (c) n = 200 and N = 800. A random sample of size 64 is taken from a normal population with µ = 51.4 and σ = 6.8. What is the probability that the mean of the sample will (a) Exceed 52.9; (b) Fall between 50.5 and 52.3; (c) Be less than 50.6? The claim that the variance of a normal population is σ2 = 25 is to be rejected if the variance of a random sample of size 16 exceeds 54.668 or is less than 12.102. What is the probability that this claim will be rejected ...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.
