Multiple Choice Question We studied a characteristic of iron. Under the normality assumption of its distribution and using its sample mean and standard deviation, we computed the following confi- dence interval [2271.7688, 2308.2312]. This interval is a confidence interval for the mean of that characteristic at a level of confidence of 90%. We are told the the sample size is 16 and the sample mean is T 2290. What is the value of the sample standard deviation s? A. 44.33...
