**YOUR TURN:**
1. Use your simulation skills to work out the power through simulation.
Write a function that does the following:
i) Draws `n` values from a random normal distribution with `mean1` and another `n` values from a normal distribution with `mean2`.
ii) Compares the means of these two samples with a *t*-test and extracts the *p*-value.
2. Replicate the function 1000 times using the parameters used in the power calculation above (that used the `power.t.test()` function).
