Question:

The manufacturer of processed deli meats reports that the standard deviation of the number of
carbohydrates in its smoked turkey breast is 0.5 gram per 2-ounce serving. A dietitian does not believe the manufacturer and randomly selects eighteen 2-ounce servings of the smoked turkey breast and determines the number of carbohydrates per serving. The standard deviation of the number of carbs is computed to be 0.62 gram per serving. Is there sufficient evidence to indicate that the standard deviation is not 0.5 gram per serving at the a = 0.05 level of significance? A normal probability plot indicates that the number of carbohydrates per serving is normally distributed.
