SAT Scores in Mathematics Are Normally Distributed with a Mean

question 59

Essay

SAT scores in Mathematics are normally distributed with a mean of 500 and a standard deviation of 100.The formula for the normal distribution is .Use the scatter plot option in a standard spreadsheet program,such as Excel,to plot the Mathematics SAT distribution using this formula.Start by entering 300 as the first SAT score in the first column (the lowest score you can get in the mathematics section as long as you fill in your name correctly),and then increment the scores by 10 until you reach 800.In the second column,use the formula for the normal distribution and calculate f(Y).Then use the scatter plot option,where you eventually remove markers and substitute these with the solid line option.

Definitions:

No-voltage Drop-out

A feature in electrical control circuits that causes the device to trip or shut off when the supply voltage falls below a certain level, enhancing safety.

Low-voltage Drop-out

A protective feature in electrical devices that causes them to turn off when voltage levels fall below a specified threshold.

Motor Stator

The motor stator is the stationary part of an electric motor, consisting of coils which create a magnetic field that induces rotation in the motor's rotor.
