Please provide some insight about this experiment I'm doing concerning goldfish growth. Basically, I've gathered all my data, and now I'm trying to figure out a way to analyze it. The experiment was basically trying to see if water volume has a direct effect on goldfish growth. I used different volumes and allowed the fish to st

4 Four separate experiments investigated the effect of three postulated amnestic agents on memory for a simple rote learning task. The task consisted of the learning of a list of 80 monosyllabic words presented to the subject at the rate of 1 per second, via a tachistoscope. The list was presented 10 times. At the end of the fin

Hello. Could you show me how to solve the attached problem. It's long, but it's still a basic statistics HW problem. The problem asks 3 questions: a) build a 95% confidence interval b) construct an ANOVA c) which pairs are different? Thanks for any assistance you can give.

1) An agronomist wants to compare the crop yield of three varieties of chickpea seeds. She plants 15 fields, five with each variety. She then measures the crop yield in bushels per acre. The results are presented in the table (see attachment). Use the following computer printout to test for the equality of mean crop yields of

A clinical researcher is interested in testing the effectiveness of an anti-depressant drug. She randomly assigned 10 depressed people to a placebo condition, additional 10 depressed people to the drug condition, and additional 10 depressed people to the double-dosage condition.
