12.Consider News Story and Original Source 1, "Alterations in Brain and Immune Function Produced by Mindfulness Meditation" (not available on the companion website). For this study, volunteers were randomly assigned to a meditation group (25 participants) or a control group (16 participants). The meditation group received an 8 week meditation training program. Both groups were given influenza shots, and their antibodies were measured. This measurement was taken after the meditation group had been practicing meditation for about 8 weeks. The researchers also measured brain activity, but this exercise will not explore that part of the study.Refer to the following warnings.If the word significant is used to try to convince you that there is an important effect or relationship, determine if the word is being used in the usual sense or in the statistical sense only.If a student is based on a very large sample size, relationships found to be statistically significant may not have much practical importance.

Is it whether or not the warnings are likely to apply to the results found in this study.

a)Yes. The warnings likely apply to this study because the study used a self selected sampling. These warnings are a concern when the sample is not random.

b)Yes. The warnings likely apply to this study because the study used a one-sided hypothesis test. These warnings are a concern when a test specifies a particular direction.

c)Yes. The warnings likely apply to this study because the sample size was small. These warnings are a concern when the sample size is too small.

d)No. The warnings are not likely apply to this study because the study used a self selected sampling. These warnings are only a concern when the sample is random.

e)No. The warnings are not likely apply to this study because the study used a one-sided hypothesis test. These warnings are only a concern when a two-sided test is used.

f)No. The warnings are not likely apply to this study because the sample size was so small. These warnings are only a concern when the sample size is large.
