Printed circuit cards are placed in a functional test after being populated with semiconductor chips. Suppose that there are 8 blue credit cards, 6 red credit cards and 4 blue debit cards in a box. It is known that color and card type are to be independent when a card is selected at random from this box. a) How many red debit cards must be present? b) Suppose that, 5 cards are randomly selected in a row with replacement. What...

Please do not use this as an example: For example, let’s say you had four groups, representing drugs A B C D, with each group composed of 20 people in each group and you’re measuring people’s cholesterol level. In your own words, describe the difference between Among Group Variation and Within Group Variation. Discuss how you would evaluate the variation and other methods to ensure that the data is appropriate to use for the test. Illustrate using a specific example.

Please use an example to explain when we should use the test. The example should specify how will you manipulate your IVs and measure your DV, and how the participants will be tested (e.g., same group of participants or different groups) (8 points): 1) Independent sample t test 2) Paired-sample t test 3) One-way ANOVA 4) 2*2 factorial ANOVA
