11 of 11 I Review | Constants Periodic Table Suppose that you want to construct a line with slope m = 3 that passes through the point (2, 1). You would begin by setting up the equation y = 3x +b If you plug in the coordinates for any point on that line, the two sides of the equation will be equal. Once you've done this, you can solve for b. What is the value of b? Express your answer as an integer. > View Available Hint(s) 8:59 PM 41% 67°F x口ツ 8/31/2021

A researcher would like to determine whether there is any relationship between students’ grades and where they choose to sit in the classroom. Specifically, the researcher suspects that the better students choose to sit in the front of the room. To test this hypothesis, the researcher asks her colleagues to help identify a sample of n = 100 students who all sit in the front row in at least one class. At the end of the semester, the grades are obtained for these students and the average grade point average is M = 3.25. For the same semester, the average grade point average for the entire college is μ = 2.95 with σ = 1.10. Use a two-tailed test with α = .01 to determine whether students who sit in the front of the classroom have significantly different grade point averages than other students.NOTICE that you are asked to use α = .01! A) sig., p<.01 B) N.S. ("not significant"), p>.01 C) sig., p>.01 D) N.S., p<.01
