Use the following values from Student's t-distribution to establish a 95% confidence interval for the population mean given a sample size of 10, a sample mean of 6.25, and a sample standard deviation of 12. Assume that the population from which the sample is drawn is normally distributed and the population variance is not known.

The 95% confidence interval is closest to:

A.A lower bound of -2.33 and an upper bound of 14.83

B.A lower bound of -2.20 and an upper bound of 14.70

C.A lower bound of -0.71 and an upper bound of 13.20
