A study was conducted in 2018 comparing the average earnings (average annual salaries) of US citizens in each state. Suppose you are hired to provide a more recent comparison of the average salaries of US citizens by state. Specifically you are tasked to determine whether the average salary in California, Washington, and Oregon are identical. Assume that the annual salaries for each state are known to be normally distributed. The data table below shows the annual salaries of the 10 individuals from your survey from each state for this year. Carry out the appropriate hypothesis test at the a = 0.0Jevel of significance to determine if the average salary for U.S. citizens in California, Washington, and Oregon are the same.
