5. (10 pts) Consider the following experiment: a soccer team in a tie-breaker has to take five shots on goal. The probability of making a goal is 0.75. You may assume that each shot is independent of the others; that is, making one shot does not affect the chances of making the next shot.
a. (2 pts) If X is the random variable representing the number of goals scored, list all possible values of X.
b. (2 pts) What is the probability that the team makes all five shots, that is, makes five out of the five goals?
c. (2 pts) What is the probability that the team makes three or more shots?
d. (2 pts) What is the expected value of the variable “number of goals scored”?
e. (2 pts). Interpret the expected value: in this situation, what does it tell you?
Please Show me the workings as well thank you!
Homework Answers
e) The expected value is the
average number of successes produced in n trials for a Binomial
distribution bin(n,p), i.e., here it is the average number of times
the goal is expected to be scored in five trials.

5. Your university star basketball player is having a difficult night of free throws. His long range probability of making free throws is 80%, however, tonight he only made 2 out of 4 shots. Fans think he was nervous. Let's use simulation to see how likely it is for him to only make 2 out of 4 shots. Random Assignment: Let numbers 0-7 represent "Making the Shot Let numbers 8, 9 represent "Missing the Shot" Use the random number generator...

Suppose you have a friend on the school basketball team but, unfortunately, he is not a good free throw shooter. Over the course of his career, he has only made 40% of his shots. Otherwise, he is a good player and gets fouled a lot so he shoots 10 free throws a game, on average. In the biggest game of the season, he does very well and makes 6 out of 10 free throw attempts. ? A. Assuming that each...

A. Introduction and Objective Every test has at least two sources of variation that affect the results of the test. The first source of variation is due to the experimental procedure, such as using two different testing machines that have different calibrations, or different observers reading the same equipment differently. This type of variation is often called the experimental error The second source of variation is inherent in the specimens (or sample population) themselves. In other words, no two specimens...
