Question
![**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 54 family practitioners in Los Angeles had mean earnings of $\bar{x} = $192,780 with a standard deviation of $43,337. 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 $\alpha = 0.05$ level of significance and the critical value method with the table.
(a) State the appropriate null and alternate hypotheses.
(b) Compute the value of the test statistic.
(c) State a conclusion. Use the $\alpha = 0.05$ level of significance.
