When you have means from two different samples, it is best to conduct ______. 1 - dependent samples t test 2 - one-sample t test 3- ANOVA 4- independent samples t test

When you are testing the difference between two means, it is not important to distinguish whether the samples are independent of each other. True

Effect size is the amount of statistical importance a particular finding has in psychological practice. the power of a study divided by the sample size. the sample size multiplied by 1 – beta.  the degree to which an experimental manipulation separates two populations.

Please help me I can’t solve this problem it’s so confusing me

Hans plays a game when he exercises. He chooses a marble from a bag of three marbles: one is blue, one is red, and one is green. Based on the marble he chooses, he completes a certain number of push-ups, as shown below. Marble Number of push-ups blue red green 10 Consider choosing a marble like sampling from a population. (The population mean of the number of push-ups is u=9.00 and the population standard deyiation is o =0.82.) (a) Suppose a sample of size 2 is randomly selected from the population, with replacement, as follows. One marble is randomly chosen, the number of push- ups is completed, and the marble is put back into the bag. Then for a second time a marble is randomly chosen and the number of push-ups is completed. There are 9 possible samples. The numbers of push-ups for several of the possible samples have been listed in the table below. Enter the numbers of push-ups for the remaining possible samples. When you are done, select "Compute". In the "Sample mean, x" column,…
