Dafna11 [192]

Your answer would be:

n = 20 pups is recorded.

known that the average birthweight for regular rats (without exposure to alcohol) is μ = 5.6 grams.

sample of n= 20 pregnant rats and mixes alcohol with their food for 2 weeks before the pups are born.

One Newborn pup randomly selected from each litter.

A.). What type of test you would use, to test the hypothesis that, alcohol consumption during pregnancy reduces birth weights? Answer, There is one treatment group, pups of alcohol-fed rats, which is being compared to a known population of regular rats, so the most appropriate statistical test is the z-test.

B.). Would you use a one - tailed, or two - tailed test? Answer, The independent variable is the alcohol condition whether, or not, / the pup’s mother received alcohol while pregnant; The dependent variable is the birth weight

C.). What would be an appropriate measure of effective, size to report?Answer, The scale of measurement for the independent variable is nominal. The scale of the dependent variable (birth weight) is ratio; effective size would be measured by Cohen's d, or r2.

Hope that helps!!!! : ) Answer: zx, Because, there is only one sample; and, it is compared to all the previous patients,/population. The σ, is given.
