Calculate an estimate for true average IAT under the described AN protocol, and do so in a way that conveys information about the reliability and precision of the estimation. Do this by calculating a 99% CI for the true average IAT under the described AN protocol. (Round your answers to two decimal places.) |kg

Question
Anorexia Nervosa (AN) is a psychiatric condition leading to substantial weight loss among women who are fearful of becoming fat. An
article used whole-body magnetic resonance imagery to determine various tissue characteristics for both an AN sample of individuals
who had undergone acute weight restoration and maintained their weight for a year and a comparable (at the outset of the study)
control sample. Here is summary data on intermuscular adipose tissue (IAT; in kg).
Condition Sample Size Sample Mean Sample SD
AN
16
0.52
0.26
Control
8
0.37
0.15
Assume that both samples were selected from normal distributions.
