Fynjy0 [20]

Answer:

(a)P(x>85.55)=0.02275

(b)P(x

Step-by-step explanation:

We are given that

Average sales for an online textbook distributor  per customer per purchase

,\mu=$67.63

Standard deviation of the amount spent on textbooks,\sigma=$8.96

(a) We have to find probability for a randomly selected customer spent more than $85.55 per purchase.

P(x>85.55)=P(\frac{x-\mu}{\sigma}>\frac{85.55-67.63}{8.96})

=P(Z>2)

=1-P(Z\leq 2)

=1-0.97725

P(x>85.55)=0.02275

(b)We have to find probability for a randomly selected customer spent less than $76.59 per purchase
