Question:

In this exercise, you are to perform a computer simulation to illustrate the of the pooled t-statistic, given in Key Fact 10.2 on page 397.
a. Simulate 1000 random samples of size 4 from a normally distributed variable with a mean of 100 and a standard deviation of 16. Then obtain the sample mean and sample standard deviation of each of the 1000 samples.
b. Simulate 1000 random samples of size 3 from a normally distributed variable with a mean of 110 and a standard deviation of 16. Then obtain the sample mean and sample standard deviation of each of the 1000 samples.
c. Determine the value of the pooled t-statistic for each of the 1000 pairs of samples obtained in parts (a) and (b).
d. Obtain a histogram of the 1000 values found in part (c).
e. Theoretically, what is the of all possible values of the pooled t-statistic?
f. Compare your results from parts (d) and (e). Distribution
The word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
