Taylor and Meredith began arguing about who did better on their tests, but they couldn't decide who did better given that they took different tests. Taylor took a test in English and earned a 73.6, and Meredith took a test in Science and earned a 67.8. Use the fact that all the students' test grades in the English class had a mean of 70.1 and a standard deviation of 9.9, and all the students' test grades in Science had a mean of 63.5 and a standard deviation of 7.9 to answer the following questions.

Suppose that 10 students have taken an exam and that the mean and median scores are both 60. (Since 10 is an even number you can assume that two scores in the middle are both 60.) Two more students take it and one scores 70 and the other scores 26. If these students are now included, what is the new mean? What is the new median?

Imagine you were chosen as the coach of the  Philippine National Men's Basketball team. You have to choose the last player to be included in the roster. You have to choose between two players. The two players have basically the same characteristics whether physical or actual game statistics. They have the same age, height, weight, wingspan, average points, rebounds, assists, steals, and blocks per game. Their only difference lies in the standard deviations for their points per game. Player 1 has a standard deviation of 5 while Player 2 has a standard deviation of 10. Who would you choose and why? 5 sentences

Miranda and Karla began arguing about who did better on their tests, but they couldn't decide who did better given that they took different tests. Miranda took a test in Social Studies and earned a 71.4, and Karla took a test in Art History and earned a 60.9. Use the fact that all the students' test grades in the Social Studies class had a mean of 75.3 and a standard deviation of 10.7, and all the students' test grades in Art History had a mean of 66.4 and a standard deviation of 10.3 to answer the following questions.a) Calculate the z-score for Miranda's test grade.z=b) Calculate the z-score for Karla's test grade.z=c) Which person did relatively better? Miranda Karla They did equally well.

Lloyd and Tara began arguing about who did better on their tests, but they couldn't decide who did better given that they took different tests. Lloyd took a test in Social Studies and earned a 77.1, and Tara took a test in Math and earned a 66.4. Use the fact that all the students' test grades in the Social Studies class had a mean of 75.5 and a standard deviation of 10.5, and all the students' test grades in Math had a mean of 65.3 and a standard deviation of 8.8 to answer the following questions.a) Calculate the z-score for Lloyd's test grade.�=b) Calculate the z-score for Tara's test grade.�=c) Which person did relatively better? Lloyd Tara They did equally well.

Mario's weekly poker winnings have a mean of $353 and a standard deviation of $67. Last week he won $185. How many standard deviations from the mean is that?

Logan and Brian began arguing about who did better on their tests, but they couldn't decide who did better given that they took different tests. Logan took a test in Art History and earned a 76.8, and Brian took a test in English and earned a 68.9. Use the fact that all the students' test grades in the Art History class had a mean of 71.9 and a standard deviation of 11.6, and all the students' test grades in English had a mean of 61 and a standard deviation of 9.4 to answer the following questions.a) Calculate the z-score for Logan's test grade.z=z= [Round your answer to two decimal places.] b) Calculate the z-score for Brian's test grade.z=z= [Round your answer to two decimal places.]c) Which person did relatively better? Logan Brian They did equally well.

So far, Walter has scores of 18, 17, 19, and 21 points for the first four science quizzes. What does he need to score on the next quiz in order to achieve an average(mean) score of 20 points per quiz?

Irondale County has two school districts, Anaconda and Copper Canyon. In the Anaconda School District, the average score of fifth graders on the Iowa Test of Basic Skills (ITBS) was 50. In the Copper Canyon School District, the average ITBS score for 5th graders was 72. Can we conclude that the average score for all fifth graders in Irondale County who took the test is 61, the mean of 50 and 72? If so, explain why. If not, tell what additional information would be needed in order calculate the mean ITBS score for all their fifth graders.

A psychologist wanted to know if students in her class were more likely to cheat if they were low achievers. She divided her 60 students into three groups (low, middle, and high) based on their mean exam score on the previous three tests. She then asked them to rate how likely they were to cheat on an exam if the opportunity presented itself with a very limited chance for consequences. The students rated their desire to cheat on a scale ranging from 1-100, with lower numbers indicating less desire to cheat. The data: Achievement_Group Cheat 1 20 1 40 1 49 1 50 1 51 1 51 1 52 1 53 1 58 1 42 1 48 1 48 1 52 1 55 1 55 1 56 1 59 1 67 1 80 1 79 2 19 2 25 2 20 2 29 2 24 2 32 2 25 2 27 2 30 2 55 2 40 2 25 2 27 2 35 2 42 2 30 2 30 2 34 2 40 2 27 3 60 3 65 3 69 3 78 3 79 3 80 3 80 3 90 3 95 3 50 3 55 3 55 3 60 3 69 3 70 3 70 3 88 3 90 3 90 3 91   Before opening the data,…
