A study was conducted to determine if the salaries of librarians from two neighboring states were equal. A sample of 100 librarians from each state was randomly selected. The mean from the first state was $29,100 with a standard deviation of $2300. The mean from the second state was $30,500 with a standard deviation of $2100. Test the hypothesis that the salaries from both states are equal. Use α =05.

Determine the test statistic to three decimal places.
