Question 2>There is a positive correlation between the length of time a tableware company polishes a dish and theprice of the dish. Does that mean that the time a plate is polished determines the price of the dish?O Yes, whenever there is evidence of a correlation between variables, we can conclude that changingone of the variable will cause a change in the other.O No, just because there is evidence of a correlation between variables, this does not mean thatchanging one will cause a change in the other.

Carl is conducting a research study and finds a significant positive correlation between a state's per capita consumption of mozzarella cheese and the number of doctoral degrees in civil engineering that are awarded (real example!). However, this association is actually caused by a third variable that Carl did not measure. This variable is known as a: Group of answer choices distractor variable confounding variable independent variable lactose intolerant variable
A scientist, who wants to study the effects of precipitation on rice crops, sets up an experiment with 4 groups of rice crops. Rice crop harvest vs. precipitation level Group B Group A 0 150 Group C Precipitation (cm/annually) Harvest (pounds/acre) 0 60 Which statement best describes the relationship between the dependent and independent variables in this study? 20 O The amount of precipitation is dependent on the amount of rice harvest. O The amount of rice harvest is positively correlated with the increase in precipitation. The amount of rice harvest is not affected by the amount of precipitation. The amount of rice harvest is negatively correlated with the increase in precipitation. 200 Group D 40 300
A student noticed that when she gets less than 8 hours of sleep at night, she scores lower on her test grades. Can one conclude that this positive correlation shows a causal relationship? OYes, because it is well known that less sleep lowers test scores OYes, because it is not a negative correlation O No, because all students get less than 8 hours of sleep at night No, because it is possible that the student gets lower test grades because of another factor, such as not studying

In a sample there are 3 male dogs and 3 female dogs. These dogs are couples such that the weight of the ith dog, and the Fi measures the weight of the ith dogs girlfriend. The correlation between M and F is exactly 1 and when the data points are graphed the slope of them are 1. Is it possible for some of these dogs to weight more than their female couple, while other dogs weight less then their female couple? And is it possible that all of the male dogs have couple female dogs that are all shorter than them?
