A. |
B. |
C. |
After looking up the z-score in the standard Normal table, why did we subtract the table probability from 1.0?

Why could we use the standard Normal table to find a probability on the mean of a random sample of eight bottles weighing more than 1.1 pounds?
A. |
B. |
C. |
True or false: We could compute both a probability on the weight of a randomly selected individual bottle and a probability on the mean weight of a random sample of eight bottles using the standard Normal table because weights of the bottles is Normally distributed.
