If we will take a sample of size n - 22, and get a sample standard deviation of s = 9, what are the two critical x values (those beyond which we would reject the null) rounded to 3 decimal places? (a) left critical value: x = -1.721 x (b) right critical value: a = 1.721 X Hint: Recall that the critical values are effectively the endpoint of the confidence interval around instead of around x. Endpoints (for a critcal value we use / instead of x): u + t . S Vn Submit
