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

We want to figure out what is the probability that a bottle of aspirin randomly picked from the production batch will weigh 593 g or less.

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) The probability that a bottle of aspirin will have weight 593 g or less is _________(your answer should have 4 decimal digits)
