Data show that men between the ages of 20 and 29 in a general population have a mean height of 69.3 inches, with a standard deviation of 2.9 inches. A baseball analyst wonders whether the standard deviation of heights of major-league baseball players is less than 2.9 inches. The heights (in inches) of 20 randomly selected players are shown in the table. Click the icon to view the data table. Test the notion at the a= 0.05 level of significance. What are the correct hypotheses for this test? The null hypothesis is Ho: 2.9. The alternative hypothesis is H, 2.9.

wants to know if it is better for Instructor Pilots to give flight students feedback in the airplane immediately after each maneuver rather than to wait till they are on the ground and debriefing. Six student pilots are selected. Each student receives immediate feedback on half of their flights and receives delayed (after landing) feedback on the other half of their flights. Average scores for the student’s evaluations are listed in the table below. Show work. Student Pilot Score for Immediate Feedback Score for Feedback Received After on the Ground Student Pilot A 4 2 Student Pilot B 3 4 Student Pilot C 5 2 Student Pilot D 3 3 Student Pilot E 5 3 Student Pilot F 5 2 a. Test the hypothesis that the student pilots receive higher evaluations on flights where they received immediate feedback compared to delayed (after landing) feedback. Use α =.05. Use the four steps of hypothesis testing. b. Calculate Omega squared (ώ2)

20 years ago 48% of parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. A recent survey found that 253 850 parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. Do parents feel differently today than they did 20 years ago? Use the a= 0.01 level of significance Find the test statistic Find the p-value Determine the conclusion for this hypothesis test.

Student Absences and Grades on the Final Exam Dr. V. noticed that the more frequently a student is late or absent from class the worse he or she performs on the final exam. He decided to investigate. Dr. V. collected a random sample of 22 students. This sample includes the number of times a student is absent and their grades on the final exam. The data can be found in the Excel file Assignment10.xlsx. Do not use any software that I did not assign. Question 1: Which or the two variables (times absent or grades on the final exam) is the independent variable and which is the dependent variable?
