You work for a pharmacy and monthly sales of asthma inhalers in your pharmacy follows a normal distribution with a mean of 191 i
grin007 [14]

Answer: -1.33 .

Step-by-step explanation:

Formula to find the Z-score :

Z=\dfrac{\text{Expected value - Mean}}{\text{Standard deviation}}

Given: Mean = 191  and Standard deviation = 21

Then , the z-score corresponding to the expected value of 163 will be :

Z=\dfrac{163-191}{21}\\\\=\dfrac{-28}{21}\approx-1.33

Hence, the z score corresponding to selling 163 inhalers is -1.33 .
