Question 3 4 pts In a test of weight loss programs, 44 adults used the Atkins weight loss program. After 12 months, their mean weight loss was determined to be 2.4 lbs., with a variance of 23.6 1b2. Assuming the sample is a simple random sample obtained from a population with a normal distribution, construct a 95% confidence interval estimate of the standard deviation of the weight loss for all such subjects. Keep your numerical answers rounded to 3 decimal...
