The Florida Tribune published an article that claimed that nurses in Tampa earn more than nurses in Dallas. You are a manager at a Tampa hospital and want to test the claim of the Tribune. You wish to test the claim at a significance level of a=0.05. So you conduct a follow up survey of 41 nurses in Tampa and 50 nurses in Dallas. You find that the sample from Tampa showed an average salary of $63200 with a standard deviation of 5300, and the sample from Dallas showed an average salary of $60700 with a standard deviation of 4800. Our claims are: Ho: µ1 – Hz = 0 На: И — Н2 > 0 (in this setup, sample 1 is the group of nurses from Tampa and sample 2 is the group of nurses from Dallas) a) What is the test statistic? b) What is the p-value? c) State your conclusion (in the context of the problem).

Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
