Aspirin is packed in 120 tab bottles with weight normally distributed with mean 600 g and standard deviation 6 g.

Rejected bottles are those whose weight differs from the mean weight by 15 g or more.That is, rejected bottles have weight either too small or too large.We want to find out how many bottles will be rejected from a daily production of 5000 bottles.

To solve this problem we need to standardize our data.

1) Do we have to calculate one z-score or two z-scores?_______(enter the number 1 or 2)

2) The negative z-score is_____(enter a number with a negative sign rounded to two decimal digits (for example: -2.00), or write NA if there is no negative z-score)

3)The positive z-score is______(enter a number with a positive sign rounded to two decimal digits (for example: +2.40), or write NA if there is no positive z-score)

4) The sketch of the normal curve that describes the question is graph_____(enter only the letter that describes the graph (for example: A))

5)How many bottles, of the 5000, do we anticipate to have to reject?_______
