Transcribed Image Text:6. This set of numbers: 6,3,5,7,5,4,3,6,4, and 8,6,4,7,6,9,7,5,6,5 represents sample scores
from a drug trail. the first 9 scores took the drug, the last 10 took a placebo. You can
either create a data frame or create two separate vectors. Either way, I want you to
compute an independent samples t-test (or between subjects) step by step as conducted in
class. You should report the sum of squares for each group, the pooled variance, the t-
score, p-value, 95% CI, test for homogeneity of variance, Cohen's d, and r2. To make
sure you are on the right track, you should get a t-score of -2.288, check your answers
using the t.test() function.
