A random sample of 86 SAT scores of students applying for merit scholarships showed an average of 1400 with a standard deviation of 240. If we want to provide a 95% confidence interval for the population mean SAT score, the degrees of freedom for reading the 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
