Given a sample mean. X = 515. a sample standard deviation, s = 9. and a sample size, n = 6. what is the absolute value of the Student's t statistic to test if the sample mean is equal to the population mean, U = 500?
Correct Answer: B
The Student's t statistic is calculated as follows: t = (X - ) / (s / n) Given: * Sample mean (X) = 515 * Population mean () = 500 * Sample standard deviation (s) = 9 * Sample size (n) = 6 t = (515 - 500) / (9 / 6) = 15 / (9 / 2.45) 3.73 References: * Montgomery, D.C., & Runger, G.C.
