A population consists of N = 5 numbers: 1, 3, 5, 6, and 7. It can be shown that the mean and standard deviation for this population are µ= 4.4 and σ = 2.15, respectively.
a. Construct a probability histogram for this population.
b. Use the random number table, Table 10 in Appendix I, to select a random sample of size n = 10 with replacement from the population. Calculate the sample mean, ̅x. Repeat this procedure, calculating the sample mean ̅x for your second sample.
(HINT: Assign the random digits 0 and 1 to the measurement x = 1; assign digits 2 and 3 to the measurement x = 3, and so on.)
c. To simulate the sampling distribution of ̅x, we have selected 50 more samples of size n = 10 with replacement, and have calculated the corresponding sample means. Construct a relative frequency histogram for these 50 values of ̅x. What is the shape of this distribution?
