REQUESTED ASSISTANCE - Would you please review the provided answer as well as the provided detailed explanation / analysis for the answer to the below confidence interval question. Is the provided answer correct, and what improvements can be made to the provided detailed explanation / analysis for the answer (please provide substantive responses)?

The sample mean is 50, the t-statistic is 1.96, and the standard error of the sample mean is 2, what is the 95% confidence interval?

ANSWER: The formula for confidence interval is upper confidence interval is UCL = Xbar + (t * SE) and lower confidence interval is LCI = Xbar - (t * SE) where Xbar is mean of the sample, t is a critical value of t and SE is a standard error. UCI = 53.92 [ UCL = Xbar + (t * SE) ] LCI = 46.08 [ LCI = Xbar - (t * SE) ]
