Is there a doctor in the house? A market research firm reported the mean annual earnings of all family practitioners in the United States was $178,258. A random sample of 50 family practitioners in Los Angeles had mean earnings of =x$192,920 with a standard deviation of $43,287. Do the data provide sufficient evidence to conclude that the mean salary for family practitioners in Los Angeles differs from the national average? Use the =α0.05 level of significance and the P-value method with the TI-84 calculator.
