Extracted text: A 2013 study was conducted to determine the energy requirements in non-obese men and women for the purpose of maintaining their current weight. The overall average total daily energy expenditure was 2,443 kcal/d. Assuming this variable follows a normal distribution with standard deviation of 397 kcal/d, conduct a test of significance to determine if this differs from a more recent study in which 95 randomly selected men and women (who claimed to have maintained their weight and body composition for a year) were measured. The sample mean is found to be 2,342 kcal/d. Use 5% level of significance.
