Scores on the critical reading part of the sat exam in a recent year were roughly normal with mean 495495 and standard deviation 118118 . you choose an srs of 100 students and average their sat critical reading scores. if you do this many times, the standard deviation of the average scores you get will be close to 118100=1.18118100=1.18 . 118100√=11.8118100=11.8 . 118100√=1.09118100=1.09 . 118118 .

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.
