Workshop 5 PSYO 2501, Fall 2017 Researchers conduct a study of 30 young (age 18) and 30 old (age 65) participants. They hypothesize that young people sleep longer on average than older people. They present the following t-test and data visualization: (41.07)-5.54, pExplanation / Answer
Solution:-

Use the unequal variance t test, also called the Welch t test. It assues that both groups of data are sampled from Gaussian populations, but does not assume those two populations have the same standard deviation.
