1. Find the indicated probability. A die with 8 sides is rolled. What is the probability of rolling a number less than 7? 2. Answer the question, considering an event to be “unusual” if its probability is less than or equal to 0.05. Assume that a study of 300 randomly selected school bus routes showed that 272 arrived on time. Is it “unusual” for a school bus to arrive late? 3. Answer the question. What is the probability of an impossible event? 4. Provide an appropriate response. 7. What is your expected value? 5. Estimate the probability of the event. Of 1735 people who came into the blood bank to give blood, 373 people had high blood pressure. Estimate the probability that the next person who comes in to give blood will have high blood pressure. 6. On a multiple choice test with 7 questions, each question has four possible answers, one of which is correct. For students who guess at all answers, find the standard deviation for the number of correct answers. 7. Find the indicated complement. The probability that Luis will pass his statistics test is 0.59. Find the probability that he will fail his statistics test.
8. Suppose you are playing a game of chance. 4 bet) if you win. Find the odds used for determining the payoff. 9. Find the indicated probability. Round to 3 decimal places. A car insurance company has determined that 9% of all drives were involved in a car accident last year. Among the 12 drives living on one particular street, 3 were involved in a car accident last year. If the 12 drives are randomly selected, what is the probability of getting 3 or more who were involved in a car accident last year? 10. Find the indicated mean. The mean number of homicides per year in one city is 37.2. Suppose a Poisson distribution will be used to find the probability that on a given day there will be fewer than 4 homicides. Find the mean of the appropriate Poisson distribution (the mean number of homicides per day). Round your answer to four decimal places. 12. Answer the question. Assume that a procedure yields a binomial distribution with a trial repeated n times. Use the binomial probability formula to find the probability of x successes given the probability of success on a single trial. 13. Find the indicated probability. 14. If a person is randomly selected, find the probability that his or her birthday is in May. 15. Solve the problem. According to a college survey, 22% of all students work full time. Analyze and solve statistical problems by applying scientific reasoning. Analyze statistical problems and develop solutions by thinking outside the box. Apply statistical methods to solve real-world problems. Communicate and present logical arguments involving statistical terms and analysis. Find something in real life that is normally distributed. Try finding a graph of it.
Mr. James Alexander, will share his poetry and motivational message. See a video and pictures from the POLYTECH event. Georgia State University will be celebrating the National Day on Writing by gathering 11 different literacy organizations on campus in the campus Courtyard. Among these organizations are GSU’s literacy journals, Writing Studio, Library, ESL tutoring services, Graduate English Association, the school newspaper, and the Digital Literacy Archive. All organizations are tasked with promoting their work and engaging students with a literacy related activity. In honor of National Writing Day, Cary District 26 will have its traditional writing exercises. But this year, they will do so in honor of Patricia Sylvester, who died in the spring after a battle with skin cancer. Sylvester, an NCTE member who was a teacher in the district for more than 30 years, taught fifth, sixth and eighth grade. She taught English at the junior high and worked as the gifted program coordinator. She also taught at the now closed Oak Knoll and Prairie Hill schools. “Pat was instrumental in getting all the schools to participate in National Writing Day,” Cary Junior High eighth-grade teacher Kathy Englund said. NCTE member Deanna Mascle, a coordinator of the event. NCTE member Lori Ungemah says. Excelsior College will celebrate ‘National Day on Writing’ (October 20) with a webinar featuring renowned writer, NCTE member Doug Downs from Montana State University. National Day on Writing” and “Nimrod Saturday!
