Answer:
1.4
Step-by-step explanation:
We have been given that the number of raisins in a box of a popular cereal is normally distributed, with a mean of 133 raisins per box and a standard deviation of 10 raisins. My cereal box has 147 raisins.
To find the z-score for this box of cereal, we will use z-score formula.
, where,
z = Z-score,
x = Sample score,
= Mean,
= Standard deviation.
Upon substituting our given values, we will get:
![z=\frac{147-133}{10}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B147-133%7D%7B10%7D)
![z=\frac{14}{10}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B14%7D%7B10%7D)
![z=1.4](https://tex.z-dn.net/?f=z%3D1.4)
Therefore, the z-score for this box of cereal is 1.4.
