What does robustness mean in hypothesis testing? And I think this is independent because the salaries of wives of doctors does not effect the salaries of other wives. Am i right? The difference between annual salaries is tested by measuring the annual salary of wives of doctors and other wives.

Use the following information to complete steps (a) through (d) below. A random sample of size n = 31 results in a sample mean of 123.3 and a sample standard deviation of 8.5. An independent sample of size n2 = 50 results in a sample mean of 129.8 and sample standard deviation of 7.3. Does this constitute sufficient evidence to conclude that the population means differ at the x = 0.005 level of significance? (a) What type of test should...

What does in sub mean??
An Iron-Nickel sample from a meteorite was placed into a velocity selector and mass spectrometer. Experimenters expect 3 primary isotopes: 56Fe, 58Ni, & 60Ni. Positive ions are accelerated by an applied potential (AV) of 3300 Volts which is the same potential difference used to create the electric field in the velocity selector, where d is 1.1 cm. 1. On the figure provided, in the velocity selector region, (A) draw the direction of the electric field....
