p-value
Now that you have created the null sampling distribution, you can use it to find the p-value associated with the original slope statistic from the twins data. Although you might first consider this to be a one-sided research question, instead, use the absolute value function for practice performing two-sided tests on a slope coefficient.
You can calculate the proportion of TRUE values in a logical vector using mean(). For example, given a numeric vector x, the proportion of cases where x is greater than or equal to 10 can be calculated using mean(x >= 10).
