Scientist cannot overcome a sampling error by choosing subjects that are very similar to each other. True or False?
Homework Answers
True
Because to overcome sampling errors, instead of choosing subjects that are very similar to each other, they need to randomise sample selection.
Sampling errors can be overcome by choosing multiple subjects and increasing the sample size.

Sometimes, objects that are very close to each other cannot be "resolved" - i.e. distinguished as different sources of light. In the assigned reading for this lecture, an equation ("Rayleigh's Criterion") was found that allows us to calculate when two objects may be resolved. Which of the following options describe correct physical properties or specific assumptions that were used to find this equation? (Choose all correct options. Unlimited, unpenalized attempts are allowed.) Light from the sources passes through some circular...
