Assignment 5 Include all answers to homework questions in one document and submit it online under Assignment 5. Textbook Homework Questions From the OpenIntro textbook (Diez, Barr, and Çetinkaya-Rundel 2015), do the following questions: 3.22, 3.32, 3.40, 3.44 . In addition, use R to answer the questions below. Additional Homework Questions For Binomial distributions, to find the probability, you can use dbinom() . For Geometric distributions, you can use dgeom() . dbinom ( 2 , 4 , 0.5 ) ## [1] 0.375 dgeom ( 4 , 0.5 ) ## [1] 0.03125 If you want to find the probability on a tail (e.g. The probability of at least 5 successes, or more than 3 successes), you can use pbinom() and pgeom() . Remember that these always give the lower tail by default! Use lower.tail = FALSE to get the upper tail. pbinom ( 2 , 4 , 0.5 ) ## [1] 0.6875 pgeom ( 4 , 0.5 ) ## [1] 0.96875 1) If you flip a fair coin 10 times, what is the probability that you get exactly 6 heads? Use the appropriate distribution to answer this question. 2) If you flip a fair coin until you get 6 heads, what is the probability that it will take exactly 10 tries?

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
