There is a strong positive linear correlation between rainfall and the number of oranges a tree produces. Does this mean that more rainfall causes orange trees to produce more fruit?A.Yes. Since rainfall and number of oranges are positively correlated, this means that more rainfall causes orange trees to produce more fruit.B.Yes. Since rainfall and number of oranges are linearly correlated, this means that more rainfall causes orange trees to produce more fruit.C.No. Any number of factors could also be affecting the number of oranges produced.D.No. Since rainfall and number of oranges are linearly correlated, this means that more rainfall causes orange trees to produce less fruit.SUBMITarrow_backPREVIOUS

There is a strong positive linear correlation between the number of clear days and the height of bean plants. Does this mean that more clear days cause the bean plants to grow taller?A.Yes. Since the number of clear days and height are linearly correlated, this means a greater number of clear days causes the bean plants to grow taller.B.No. Any number of factors could also be affecting the height of the bean plants.C.No. Since the number of clear days and height are linearly correlated, this means a smaller number of clear days causes the bean plants to grow taller.D.Yes. Since the number of clear days and height are positively correlated, this means a greater number of clear days causes the bean plants to grow taller.

A dataset includes two variables for a city in the past 40 years: the number of high school graduates and the consumption of pizzas each year. You find that the two variables are positively correlated.Which of the following statement best describes such a correlation?i)High school graduates love eating pizzas.ii)If we increase the number of high school graduates, we would expect an increase in the pizza consumption.iii)As there might be an increase in the general population of the city, the number of high school graduates appears to be positively correlated with the pizza consumption. iv)Pizza stores should target high schools to increase their revenue. Question 8Answera.iiib.iic.i, ii and ivd.i and iie.None of the listed statements
