Obesity in adult males is associated with lower levels of sex hormone. A study investigated a possible link between obesity and plasma testosterone concentrations in adolescent males between the ages of 14 and 20 years. Plasma testosterone level is measured in nanomoles per liter of blood (nmol/1) for a sample of 25 obese adolescent males. The sample mean is 0.26 nmol/l, and the sample standard deviation is 0.11 nmol/l a) What distribution does the mean testosterone level in the sample...
