As in previous labs, RESIST THE URGE TO CODE! Determine what data will be necessary in order to complete this task. Then design the steps necessary to process that data. Do you need if statements? Do you need loops? Do you need if statements within your loops?

Write a program that prompts the user to enter the number of students and each student’s name and score, and finally displays the student with the highest score (display the student’s name and score). Also calculate the average score and indicate by how much the highest score differs from the average. Use a for loop.  

Test Data:

            Ben Simmons             70

            Carson Wentz             80

            Joel Embiid                 90

            Bryce Harper             75

13) Why do some baseball teams have many wins, but are not as profitable as some teams who do not have as good of a win-loss record?

Let X represent the number of times a student visits a bookstore in a one-month period. Assume that the probability distribution of X is as follows: Let X represent the number of times a student visits a bookstore in a one-month period. Assume that the probability distribution of X is as follows:

1. What is the probability that the student visits the bookstore at least twice in a month?

(1 mark)

2. What is the probability that the student visits the bookstore at most ones in a month?

​(a) Explain why this is a binomial experiment.
​(b) Find and interpret the probability that exactly 9 flights are on time.
​(c) Find and interpret the probability that fewer than 9 flights are on time.
​(d) Find and interpret the probability that at least 9 flights are on time.
​(e) Find and interpret the probability that between 7 and 9 ​flights, inclusive, are on time.

Identify the statements that explain why this is a binomial experiment. Select all that apply.

A. There are two mutually exclusive​ outcomes, success or failure.

B. The experiment is performed until a desired number of successes is reached.

C. There are three mutually exclusive possibly​ outcomes, arriving​ on-time, arriving​ early, and arriving late.

D. Each trial depends on the previous trial.

E. The probability of success is the same for each trial of the experiment.

F. The experiment is performed a fixed number of times.

G. The trials are independent.

b) The probability that exactly 9 flights are on time is

In 100 trials of this​ experiment, it is expected about __ to result in exactly 9 flights being on time.

c) The probability that fewer than 9 flights are on time is ____

In 100 trials of this​ experiment, it is expected about ___ to result in at least 9 flights being on time.

e) The probability that between 7 and 9 ​flights, inclusive, are on time is ___

In 100 trials of this​ experiment, it is expected about ___ to result in between 7 and 9 ​flights, inclusive, being on time.​(Round to the nearest whole number as​ needed.)

2.  Innocent until proven guilty? In Japanese criminal trials, about 95% of the defendants are found guilty. In the United States, about 60% of the defendants are found guilty in criminal trials. (Source: The Book of Risks, by Larry Laudan, John Wiley and Sons) Suppose you are a news reporter following ten criminal trials. (For each answer, enter a number.)

(a) If the trials were in Japan, what is the probability that all the defendants would be found guilty? (Round your answer to three decimal places.)
