A study was being conducted to see if people who have no college degree have a lower mean salary than those who do have a college degree. A random sample of 70 people with no college degree was taken and their mean salary was $36,950 with a standard deviation of $4,375. A random sample of 75 people with a college degree was taken and their mean salary was $41,520 with a standard deviation of $3,415. Determine the appropriate formula and calculator function that would be used to test the claim that people with no college degree have a lower mean salary at the a= 0.05 level of significance. d T-Test sal√n to = Fo= Zo to 2-SampFTest P1-P₂ √(1-6), + 1 n₁ 7₂ (x₁-x₂)-(H₁-H₂) $₁² $₂² n₁ n₂ 2-PropZTest 2-Samp TTest
