So we could say minus 1.29 times the standard deviation. And they tell us up here the standard deviation is 11 seconds. So it's going to be 1.29 times 11. And this is going to be equal to 1.29 times 11 is equal to 14.19. And then I'll make that negative and then add that to 185. Plus 185 is equal to 170.81. 170.81.
