... number of values. The median is the value that divides the distribution in half, i.e., if the observations are arranged in increasing order, the median is the middle observation. If there is an even number of observations, the average of the two middle ordered values is taken. The mode is defined as ...

... (e) The test statistic for a two-sided test of a proportion is 2.5. Will the P-value be larger if: (1) n = 50 or (2) n = 100 (for the same value of the test statistic)? (f) In a two-sided test for a proportion, how do we get larger power with larger sample size (for the same hypothesis, and same sam ...
