8. Is there a doctor in the house? The Bureau of Labor Statistics reported that in May 2009, the mean annual earnings of all family practitioners in the US was $168,550. A random sample of 55 family practitioners in Missouri that month had mean earnings of $154,590 with a std dev of $42,750. Do the data provide sufficient evidence to conclude that the mean salary for family practitioners in Missouri is less than the national average?
