A random sample of 68 SAT scores of students applying for merit scholarships showed an average of 1400 with a standard deviation of 220. If we want to provide a 95% confidence interval for the population mean SAT score, the degrees of freedom for reading the t value is The "t" value (3 decimals) for a 95% confidence interval estimation is The margin of error (3 decimals) at 95% confidence is The 95% confidence interval (3 decimals) for the SAT scores goes from up to

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
