1. IKEA is a Swedish company that sells ready-to-assemble furniture. Shoppers contact customer service to find a nearby store, for online shipping questions, and even for help with assembly. IKEA classifies all telephone calls to its customer support staff by the amount of time the customer is on hold. If the customer is on hold for no more than 60 seconds, then the call is classified as successful (which feels more like a miracle). The supervisor in technical support claims 65% of all calls are successful.Suppose 15 calls are selected at random.Round your answer to three decimal places as necessary.

A. 2 points) Use the binomial probability distribution to find the probability11of the calls are successful.

B. (3 points) Use the binomial probability distribution to find the probability more than12of the calls are successful.

C. (3 points) Use the binomial probability distribution to find the probability of at least 9of the calls are successful.

D. (3 points) Use the binomial probability distribution to find the probability at most10of the calls are successful.

E. (3 points) Use the binomial probability distribution to find the probability fewer than8of the calls are successful.

F. (2 points) Calculate the expected value of this distribution.

G. (2 points) Calculate the standard deviation of this distribution.
