35 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 premedicalstudent 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 thismood 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 thatwould result from this hypothesis test (Be sure to round your answer to the second decimal place)."QUESTION 35"A research report describing the results from a independent t-test included the following statement: t(8) = 2.78, p = .04. Based on this report, using a standard alphalevel, is this effect statistically significant?"O "no, because p must be less than .001 to be statistically significant"O "yes, because p must be less than .001 to be statistically significant"O "no, because p must be less than .05 to be statistically significant"O "yes, because p must be less than .05 to be statistically significant"4U 9RT642414

35. The given p-value is 0.04.The standard alpha is 0.05. Since the p-value is less than 0.05 indicating that the null hypothesis is rejected and this effect statistically significant. Thus, yes, because p must be less than 0.05 to be statistically significant. Correct Answer: Option 4.
