ok when your done make it easy
Answer:
Step-by-step explanation:
a. The study is an experiment because it assigns people or things to groups and aims to notice if there is a difference in the change in cortisol level depending on the type of interaction with mom. This also occurs where researchers introduce an intervention and then study the effects of such intervention
In an observational study, measurement or members of a sample are surveyed of a sample without trying to affect them. this also occurs where researchers observe the effect of a risk factor or other intervention without trying to change who is or isn’t exposed to it.
b. The total degree of freedom is calculated using the formula N - 1 where N is the total number of girls (68). Thus, we have N - 1 = 68 - 1 = 67.
The degree of freedom for groups is k - 1 where k is the number of girls in each equal-sized group (which is 68/4 groups = 17 girls in each group). Thus, we have k - 1 = 17 - 1 = 16
The error degree of freedom is calculated using the formula N - k where N is the total number of girls (68) and k is the number of groups (4 equal sized groups) in the sample. Thus, we have N - k = 68 - 4 = 64.
c. Was the p-value of the original ANOVA test above or below 0.05?
The p-value of the original ANOVA test was below 0.05 because there was a highly significant level of cortisol observed after the activities.
