Is the following results section correct?  A single sample t test was conducted to measure the affect of a drug on short-term memory in 8 randomly selected participants. Each participant was given the drug, and then told to memorize a list of 10 words. After 15 minutes, they were tested for retention. The result was statistically significant, t (7) = 4.32, p = .003, two-tailed., 95% CI [6.9054, 9.0946]. The words remembered in the task (M = 8.00, SD = 1.30) differed significantly from the population (m = 6) with a large effect size, d = 1.31. A) Is it correct in APA style?  B) Is it correct as per the outputs shown on SPSS?
