The average production cost for major movies is 66 million dollars and the standard deviation is 18 million dollars. Assume the production cost distribution is normal. Suppose that 7 randomly selected major movies are researched. Answer the following questions, Give your answers in millions of dollars, not dollars. Round all answers to 4 decimal places where possible. a. What is the distribution of X?XN ( b. What is the distribution of x?xN ( c. For a single randomly selected movie, find the probability that this movie's production cost is between 64 and 68 million dollars. d. For the group of 7 movies, find the probability that the average production cost is between 64 and 68 million dollars. e. For part d), is the assumption of normal necessary? Yes No.

1. The below code,in C language please, needs to be completed so that when a serial terminal is
open, echoing characters will turn the LED on or off. Typing ON to turn them on, and typing OFF
to turn them off.
