QUESTION 33 "A clinican has found a significant effect of a new drug and wants to know the effect size. If the population mean =140 with a standard deviation = 6.5 and the clinical observed a sample of n = 64 had a mean = 136, then what would be the effect size in terms of Cohen's d?" O 0.81 O -4.92 O -0.62 O 0.62 QUESTION 34 "Lula-Rae Inc. claims that ingesting a concoction of lemon and lavender essential oils will significantly elevate mood in consumers. To test this, a skeptical premedical student selects a sample of 49 participants. Each participant drinks a mixture of the essential oils and then completes a mood inventory. The population score on this mood inventory has a mean = 49 with a standard deviation = 10. The sample of n = 49 participants had a mean score of M = 50. Calculate the z-observed value that would result from this hypothesis test (Be sure to round your answer to the second decimal place).
