Problem #4 (actual data from someone I know) Over a ten-year period, the fasting cholesterol level of an individual had a Mean = 198.8 mg,dl with a Std. Dev. = 8.7. Within that time span, there was a six-month period where the primary diet was Vegan. Over that six months, the fasting cholesterol level was measured twice, and showed a Mean = 162. Was there a difference in fasting cholesterol levels while on the Vegan diet? (conduct a 1-sided test) Is there enough evidence to support a general conclusion that would hold up to a scientific review? Why or Why Not? What would you do as the next steps
