Joe is attempting basketball free throws. The probability of success on each attempt is 0.39 and his consecutive attempts are independent of each other. Answer the following questions. If Joe attempts three free throws, what is the probability he has at least one success? (a) Let X be the number of attempts required for Joe to observe his first successful free throw. What kind of discrete random distribution for X? (Binomial, Poisson, or none of them) (b) If Joe attempts...

Will rate!! Suppose 81% of all students taking a beginning programning course fail to get their first program to run on first submission. Consider a group of S such students,where each student's success is independent from the other and the chance each student fails on their first try is consistent. (Round answers to three decimal places.) (a) If X is the number of students whose program fails on the first run, then X comes from a binomial distribution with: n-...
Question 1 Suppose that an experimenti setup to roll a fair 2. Suppose this experiment is done 25 times. While showing work and stating methods for calcula setup to roll a fair six-sided die A Success is recorded if the die shows a lor using a calculator, be sure to state the distribution) where work cannot be shown, find: (a) The probability that we have at most successes (5 points) 74. A particular brand of tires claims that its deluxe...
5. (20 pts) Suppose on a given college campus 45% of the students own an iPhone, 50% an Android smartphone and 5% some other type of phone. Let X=the number of students in a simple random sample of 15 students who own an iPhone. A. What is the probability distribution of X? Note: If this is a well-known distribution it is sufficient to name the distribution and identify the value of the parameters B. Find the probability that 8 students...
conducted to determine success rates of students enrolled in the Statistics courses offered at South Plains College for the fall semester of 2015. A random sample of 14 students was taken, and we recorded each student's age, final average, gender, # hours worked per week, race, and t attended this semester). Use the results from the following table to answer all parts of #2. he attendance record (# of classes not Age 20 18 19 Final Average Gender # Hrs...
A box contains 140 USB drives 38 of which are defective. consider drawing a non-defective USB drive to be a success. if 25 USB drives are randomly selected without replacement, the results do not form a binomial distribution for which reasons select all that apply. a. There is not a fixed number of trials. b. The probability of success is not the same in each trial. c. each trial has more than two possible outcomes. d. The trials are dependent...
A study was conducted to determine success rates of students enrolled in the Statistics courses offered at South Plains College for the fall semester of 2015. A random sample of 14 students was taken, and we recorded each student’s age, final average, gender, # hours worked per week, race, and the attendance record (# of classes not attended this semester). Use the results from the following table to answer all parts of #2 f. For the age variable, construct 3...
