Answer:
Step-by-step explanation:
given that a certain test preparation course is designed to help students improve their scores on the LSAT exam. A mock exam is given at the beginning and end of the course to determine the effectiveness of the course. The following measurements are the net change in 6 students' scores on the exam after completing the course:
We find
Mean 13.66666667 = 13.7
Standard Error 1.801234145
Margin of error for 90% = 1.645*std error = 2.963
Confidence interval = Mean ±Margin of error
=(10.704, 16.630)
Sample mean = 13.7
The answer is letter C and E.
For A and B, they look like a linear transformation, however
when you add the constants, it will not zero out. For letter D, it is not a linear
transformation because of the scalar multiplication. The value given in D is an
absolute value, so whether or not you multiply this, it will not result to the
same number.
I’ll explain how to graph them since there are quite a few problems. :)
The easiest way to graph is to first put down the y-axis, which is the end number on the end of the equation. For example, on the first problem the y-intercept is 5, so for this point you would just plot down (0,5).
Next you would just plot down points that follow the slope, which is the first number in the equation, and in the first problem it is 1/2.
The top number determines if you go up and down the bottom number determines where you go right. *only when the slope is negative will you go down for the top part of the slope*
For example, in the first problem you would start plotting from where you put your y-axis and go 1 up and 2 down to plot your next point. You would follow this trend another time or two until you can make your line.
