Aspirin is packed in 150 tab bottles with weight normally distributed with mean 750g and standard deviation 8g.

Rejected bottles are those whose weight differs from the mean weight by 18g 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 10,000 bottles.

To solve this problem we need to standardize our data.

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

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)
