STAT 500 Lessons 3, 4, & Minitab NAME: KYLE SHANK Answer the following questions showing all work. For the questions that require Minitab, include the appropriate output along with an explanation. Output without explanation will not receive full credit. Round all answers to 3 decimal places. If you have any questions, post them to the course discussion board. 1. Over the course of two weeks a restaurant kept track of the number of tables who order an appetizer. They found that 420 out of 1,400 tables during that time ordered an appetizer. Assume that event A = ordered an appetizer. [20 points] A. Compute P(A). P(A) = 420/1400 = 3/10 = 0.3 B. Compute the complement of P(A). P(A c ) = (1400-420)/1400 = 980/1400 = 7/10 = 0.7 C. Is this probability best described as a relative frequency probability or subjective probability? Explain why. This probability is best described as a relative frequency probability. It is not subjective in that we are not testing any prior held positions, beliefs, or assumptions on the probabilities of any given table ordering an appetizer – we are instead taking the empirical approach. D If you were to randomly select 3 tables, what is the probability that all three ordered an appetizer? P(3 tables ordering an appetizer) = (3/10) 3 = 27/1000 = 0.027 E. If you were to randomly select 3 tables, what is the probability that at least one ordered an appetizer? P( At least one appetizer) = 1 – P(No appetizers) 3 = 1 – (0.7) 3 = 657/1000 = 0.657 2.

    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.
