C. Stratified Sampling
Step-by-step explanation:
Based on the information provided within the question it can be said that the sampling method that is being used in this scenario is called Stratified Sampling. This method refers to when a researcher divides a population into various different groups and then chose a predefined number of samples at random from each group. Which is exactly what is happening in this scenario since Carrie divided her day into three parts (groups) and measured her mood twice at random for each part of the day (group).
Answer:
Yes, Holmes is correct.
Step-by-step explanation:
Let's separate each statement of Holmes: (they are all true)
- If Mrs. Smith is lying then Moriarty has not escaped.
- Either Moriarty is dead or he is really Jones.
- If Moriarty is really Jones then he has escaped.
- I am convinced Mrs. Smith is lying.
If we start with the last one, we know that Mrs. Smith is lying. That takes us to the first one, Mrs. Smith IS lying, so Moriarty has not escaped.
If we look the second one, either Moriarty is dead or he is really Jones.
If he is really Jones, that takes us to the third statement that says that Moriarty has escaped. But we know from the first statement that he hasn't escaped, so he can't be Jones.
So, going back to the second statement, Moriarty is dead.
