A labour market researcher wants to investigate if there is a difference in the mean annual salary of government workers
A labour market researcher wants to investigate if there is adifference in the mean annual salary of government workers andprivate-sector workers in similar jobs. A random sample of 35government employees doing the same job as their private-sectorcounterparts had a mean annual salary of $66,700. A randomsample of 32 similar-type private-sector jobs had a mean annualsalary of $60,400. Assume that the population standard deviationsof the government and private-sector salaries are $12,000 and$11,000 respectively. What is the standard error of the samplingdistribution of the difference between sample means equalto? Do NOT include the $ sign or any spaces or commasin your answer. Round your answer to 2 decimal places.
