Question
Chapter 2, Problem 2.4P
Interpretation Introduction
Interpretation:
To estimate number of steps it would take to walk from earth to Alpha Centauri.
Concept introduction:
When making this calculation, we must consider the units of measurement involved in our equation and convert them accordingly if there are multiple of them. For the purposes of this problem, we assume that a typical step is 3 feet.

Two-Step Algebra
a =b+ cd lne
In order to solve the equation above for d, you must:
Step One
Add the same expression to each side of the equation to leave the term that includes the variable by itself on the right-hand side of the
expression:
-b ta =-bv +b+ cd Ine
Step Two
Multiply both sides of the equation by the same expression:
x(a - b) = xcd Ine
The resulting equation is:

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!
