Assume that math test scores are normally distributed with a mean of 400 and a standard deviation of 80. If you were to score 240 on this exam what percentage of those taking the test scored below you, round to nearest tenth as needed
Three cars are driving on a racetrack. The mean speed of the three cars is 100 miles per hour. Car X drives 109 miles per hour and Car Y drives 117 miles per hour. Use the mean to estimate the speed of Car Z. What is the actual speed of Car Z?
Alexander Borbely is a professor at the University of Zurich Medical School, where he is director of the sleep laboratory. The histogram in the figure below is based on information from his book Secrets of Sleep. The histogram displays hours of sleep per day for a random sample of 200 subjects. Estimate the mean hours of sleep, standard deviation of hours of sleep and coefficient of variation. (Enter mean to 1 decimal place, s and CV to 2 decimal places.)
answer only 8-94
in 2020, a sample of 12 monarchs had an average wingspan of 6.3 cm. this year a new sample of 12 had an average wingspan of 7.2 cm based on years of data, we know the population standard deviation is 2.2 cm. compare the means from 2020 and 2021. write a conclusion with a statistics and probability in parenthesis
f Suppose that you take an exam with 391 possible points and are told that that mean score is 270 and that the standard deviation is 22. You are also told that you got 346. Did you do well on the exam? Explain your answer. Determine the z-score and interpret this score. A score of 346 has a z-score of. This is standard deviations the mean for this exam. The this score is the mean, this is a score. (Round to two decimal places as needed.) standard deviations states that approximately 99.7% of the observations lie within standard deviations of the mean. Sine
Three cars are driving on a racetrack. The mean speed of the three cars is 100 miles per hour. Car X drives 109 miles per hour and Car Y drives 117 miles per hour. Use the mean to estimate the speed of Car Z. Then find the actual speed of Car Z.
You are going to convert raw scores to z scores. The z scores are -2, -1, 0, +1, +2. The raw scores are 8, 10, 17, 22, 6, 20, 21, 22, 19, 30. How are the raw scores equivalent to z scores? Make sure to minus the mean then divide by the standard deviation X-M/SD
kamal is in his first semester at a university and is taking a calculus course with a large enrollment. He just took the first midterm exam and is nervous about his score. Among all the students in the course, the mean of the exam was 65 with a standard deviation of 9. Greg scored a 94 on this exam. Find the z-score of Greg's exam score relative to the exam scores among all the students in the course. Round your answer to two decimal places.
