I'm interested in a t-test of looking at the means for the <30 group in comparison to the other age groups. Do I need to run four t tests, one for <30 with each age group? The data below details the percentage of giving by age group for each of the 32 years listed. Thank you!

There are three (3) cases for handling the comparison of means using the Student’s t-test. For each of the scenarios listed below, identify which case (i.e. Case #1, #2, or #3) you would use in order to determine if the results agree “within experimental error”: Provide a brief explanation to receive full credit!

I'm currently looking at this figure, but I'm not sure how to interpret it. If I'm not mistaken, the energy loss of the muon (This is a muon that penetrates copper) is on the y-axis. But does that just mean, that if my muon has energy of around 0.5 GeV, then it has a stopping power around 2 MeV cm2/g (Minimum ionization), which means it loses that amount of energy pr. cm2/g? To me that just seems a bit "linear"....

To investigate this, an experimenter split 14 recent parolees into "high skill and self-esteem" and "low skill and self-esteem" groups. Three months later, employers were asked to rate each parolee’s job performance on a standard test that gives ratings from 1 to 10, with 10 being the highest. The following ratings...

I'm looking at the below webpage. The question states "On 01/30/12, prior to...., Rice declared a 100% stock dividend on c/s". I see mathematically what happens but I don't understand why. How come two years of COMMON stock dividends are issued not just one year? It isn't cumulative preferred stock. There's something about issuing common stock dividends I must not understand. Could you please connect the dots? https://www.chegg.com/homework-help/questions-and-answers/december-31-2010-rice-company-300-000-shares-common-stock-10-000-shares-5-100-par-value-cu-q1083710.

In a t-test, when we see a difference in the means but our test leads us to accept the null hypothesis, we: Select one: 1. claim that a significant difference exists between groups. 2. have obtained a t-value greater than our critical t-value. 3. have committed a Type 1 error. 4. conclude that the difference is a result of the sampling error.
