At a large department store, the average number of years of employment for a cashier is 5.7 with a standard deviation of 1.8 years. if the number of years of employment at this department store is normally distributed, what is the probability that a cashier selected at random has worked at the store for over 10 years?

  0.0019

Step-by-step explanation:

Let x be the random variable that represents the number of years of employment at this department store.

Given : The number of years of employment at this department store is normally distributed,

Population mean :

Standard deviation :

Z-score :

Now, the z-value corresponding to 10 :  

P-value =

Hence, the probability that a cashier selected at random has worked at the store for over 10 years = 0.0019

answer:   y=2x-3
