1. Cans of LaCroix are supposed to contain 355 milliliters (ml). There is some variation for each can because the filling machinery is not perfectly precise. An inspector measures the contents (in ml) of 12 randomly selected cans from a single day's production. 357 349 350 351 352 353 354 355 356 LaCroix volume (ml) = 352.9 s, -2.19 Do these data provide convincing evidence at the a= 0.01 significance level that the mean amount of LaCroix in all the cans filled that day is less than the target value of 355 ml?
