"Dr. Broadus found a significant effect of alcohol consuption on dance partner attractiveness ratings using a dependent sample t-test. If he observed a mean difference of 2.96 with a sample variance value of 21.4 after alcohol consuption, what would be the effecti size in terms of Cohen's d?" d = 0.64 d = 0.14 d = -0.64 d = 0.44

QUESTION 24 "A single sample t-test with a df - 27 determined that the mean of 45.75 was significantly higher after treatment. Assuming the standard error - 0.83, construct a 99% confidence interval to estimate the population mean difference." O 99% CI = 43.45 to 48.05 O 99% CI = 44.05 to 47.45 O 99% CI = 44.34 to 47.16 O 99% CI = 42.91 to 48,.59 QUESTION 25 "Dr. Broadus found a significant effect of alcohol consuption on dance partner attractiveness ratings using a dependent sample t-test.
