Assume the federal government releases an David Bourgeois Saylor

Question 33 / 187: Assume the federal government releases an estimate of an increase of 250,000 new jobs for the month of January. However, a sample taken of 20 economists provides an average estimated number of new jobs totaling 266,000, with a sample standard deviation of 24,000. Treat the federal government's estimate as the population mean. Say you wish to test if the economists' estimate represents a statistically significant increase over the federal government's estimate for the job increase. Which of the following accurately represents the null hypothesis of that test?

A $$ H_0: \mu \leq 250,000 $$

B $$ H_0: \mu \geq 250,000 $$

C $$ H_0: \mu = 250,000 $$

D $$ H_0: \mu = 0 $$
