Give an example of variables that have correlation but no causation exists?  Explain why these variables have correlation.  Could there be a lurking variable that these variables are both tied to/or do you think this correlation was caused by p-hacking?  [2-3 sentence or a graph] You may NOT use the ice cream/crime example AND you may not copy information verbatim from websites.  You may look at  https://stats.stackexchange.com/questions/36/examples-for-teaching-correlation-does-not-mean-causation for examples but you need to (at a minimum) put what you find in your own words and explain what the true cause of the relationship is.  In the ice cream/crime example it was found that in a particular city that when ice cream consumption went up so did petty crime (stealing/larceny).  The true cause was that it was summer and it was hot (and kids didn't have school to keep them busy). How do we decide if the correlation coefficient is close enough to ±±1 to declare that there is…

The population of India can be modeled by the function P(t) = 1462(1 +0.0177) where P(t) measures the population in millions andt represents the number of years since 2000. 1. Using this model, what was the population of India in 2009? 2. Predict the population of India in 2019. 3. If this growth rate continues, in what year will the population of India reach 2 billion people? Hint:
