The GPA of accounting students in a university is known to be normally distributed. A random sample of 20 accounting students results in a mean of 2.92 and a standard deviation of 0.16 . Construct the 95% confidence interval for the mean GPA of all accounting students at this university. Multiple Choice 2.92+-1.729((0.16)/(sqrt(20))) 2.92+-1.96((0.16)/(sqrt(20))) 2.92+-2.086((0.16)/(sqrt(20))) 2.92+-2.093((0.16)/(sqrt(20))) The GPA of accounting students in a university is known to be normally distributed. A random sample of 20 accounting students results in a mean of 2.92 and a standard deviation of 0.16.
