Answer:
The most appropriate statistical test to use to compare the mood scores from the different groups is independent sample t-test.
Step-by-step explanation:
The Independent Samples t-test examines the means of two independent groups to see if statistical evidence exists to show that the related population means differ significantly.
The Independent Samples t-test is also known as Independent t-test, Independent Two-sample t-test, and among others.
It should be note that only two (and only two) groups can be compared using the Independent Samples t-test. It is not possible to use it to make comparisons between more than two groups.
Therefore, the most appropriate statistical test to use to compare the mood scores from the different groups is independent sample t-test.

Answer: 8=x days
Step-by-step explanation:
(4/5)mile=((1/10)mile)(x days)
Let's cancel units...
(4/5)mile=((1/10)mile)(x days)
4/5=(1/10)x days
Let's proceed to isolate x by multiplying both sides by 10...
(10)(4/5)=(10)(1/10)(x days)
40/5=x days
8=x days
