Note that these column vectors vertically indicate the coordinates of X (on the left) and Y (on the right). The coordinates of each vector are provided within round parentheses, separated by commas. Compute the p-value for a two-sided, unpaired two-sample t-test with unequal variances against the null hypothesis H0 : X ̄ “ Y ̄ towards the alter- native hypothesis that X ̄ “ Y ̄. Does the p-value you compute reject the null hypothesis at an alpha level of 0.05?
