Question:
A study examined the effect of red pepper capsules on resting energy expenditure. Subjects were tested for resting energy expenditure (kilocalories (kcal) per hour) under two conditions: 1) after taking red pepper capsules, and 2) after taking placebo capsules. The order of capsule consumption was randomized, and the study was double blind. The 95% confidence interval for the difference in resting energy under the two conditions was -12.2 to 15.7 kcal per hour. Would the null hypothesis be rejected at alpha = 0.05 (two-tailed test).
