You call one of your friends to go to a movie on Friday night. He declines your invitation, stating that he needs to study for his upcoming exam on Monday. He states that he scores higher on a exam when he studies for the exam. Despite your efforts to convince him to go to the movie, he stays at home to study for his exam. You decide to use the scientific method to test the hypothesis that students who study for an exam tend to score higher than students who do not study for an exam. In what order should you conduct the following steps to test your hypothesis?
After the exam has been completed, you have the students anonymously fill out a questionnaire asking about their study habits for the exam and the grade they earned on the exam. From the surveys, you randomly select 10 students who studied for the exam and 10 students who did not study for the exam. You create the table showing the students' exam grades given here:
Grades of 10 students who studied
Exam grade 94 96 90 88 88 100 77 96 98 83
Grades of 10 students who did not study
Exam grade 65 73 70 64 55 49 89 67 76 52
What was the average exam grade for each set of students?

Listen base your answer to the question on the information below. propane is a fuel that is sold in rigid, pressurized cylinders. most of the propane in a cylinder is liquid, with gas in the space above the liquid level. when propane is released from the cylinder, the propane leaves the cylinder as a gas. propane gas is used as a fuel by mixing it with oxygen in the air and igniting the mixture, as represented by the balanced equation below. c3h8(g) + 5o2(g) → 3co2(g) + 4h2o() + 2219.2 kja small amount of methanethiol, which has a distinct odor, is added to the propane to consumers detect a propane leak. in methanethiol, the odor is caused by the thiol functional group (–sh). methanethiol, ch3sh, has a structure that is very similar to the structure of methanol. what is the correct structural formula for a molecule of methanethiol
