Think about doing a One-Sample t-test. Think about doing step three, calculating the t-obtained. Which option below contains the correct t-obtained, given all the other numbers in that option? Group of answer choices General population mean = 15.1, sample size = 18, sample mean = 19.00, sample standard deviation = 2.65, standard error = 1.00, t-obtained = 3.89. General population mean = 15.1, sample size = 7, sample mean = 19.00, sample standard deviation = 2.65, standard error = 1.00, t-obtained = 3.89. General population mean = 15.1, sample size = 7, sample mean = 19.00, sample standard deviation = 4.47, standard error = 1.00, t-obtained = 3.89. General population mean = 20.1, sample size = 7, sample mean = 19.00, sample standard deviation = 2.65, standard error = 1.00, t-obtained = 3.89
