Answer: a. 7
Step-by-step explanation: <u>Degrees</u> <u>of</u> <u>Freedom</u> is the number of values "allowed" to vary. For example:
In the experiment above, the sample has 8 tobacco leaves. Two strains will be applied to each leaf. The decision of which strain goes to the right or left is random. Each strain have 7 possible leaves it can be applied, because, for the last, the eight leaf, there is no choice.
Therefore, the degrees of freedom for this experiment is 7.
It can also be calculated as
df = n - 1
df = 8 - 1
df = 7
