6. [15 points total] The following table presents information on 4 different random samples from the same population. Imagine that each sample is investigating a two-tailed null hvpothesis that the mean is 79 and that the sample meam in each sample is 80; and the standard deviation in each sample is 10. Some of the samples would reject the null hypothesis, other would not. Report what this table is supposed to illustrate, and explain what makes the illustrated phenomena occur. The following table reports the test statistics corresponding to a single-sample test of the hypothesized mean computed from 4 different random samples of various sizes (with each sample having the same mean and standard deviation as reported above) Sample Test Statistic observed) Size 101 201 501 1,001 1.00 1.41 2.23 3.16 a) [5 points] What does this table illustrate? Why doesn't the same sample mean provide the same test outcome? b) [10 points] What makes this phenomena occur
