QUESTION:

Are the trials independent? For each of the following situations, identify the trials as independent or not. Explain your answers. (a) You record the outside temperature in your town at noon on Groundhog Day, February 2, each year for the next 5 years. (b) The number of tweets that you receive on the next 10 Mondays. (c) Your grades in the five courses that you are taking this semester

ANSWER:

Step 1 of 3

So the temperature of 5 years, which are five trials, are.
