Assignment Task :

Calculate a number of required replicates for a range of mean differences,

Let $m_1$ be a sequence of means from 320-420, incremented by 10. Let $m_2$ be 270. Assume a pooled standard deviation of 150.

Calculate Cohen's $d$ for the pairs of means ${320 - 270, 330 - 270, ...., 420 - 270}$, letting $s_i = s_j = s_{pooled}$.

Calculate the required replicates for these same pairs of means. You may reuse code or functions from previous homework at your discretion.

To show your results, either create and print a matrix with one colum for effect size and one column for replicates, or plot required replicates versus effect size (effect size will be the independent variable).

What does this tell you about the number of observations required to detect medium-size effects? You may include reference lines in your plot to illustrate.
