which scenarios have a negative correlation? check all that apply. the number of calories consumed and the amount of weight lost by a person the temperature outside and the number of pool guests the number of children assigned to a class and the number of desks the price of rice and the number of penguins at the south pole the thickness of the ice on a lake and the likelihood of falling through the ice

Answer

Explanation:

Step1: Understand negative - correlation

Negative correlation means that as one variable increases, the other variable decreases.

Step2: Analyze each scenario

  • For "the number of calories consumed and the amount of weight lost by a person": As the number of calories consumed increases, the amount of weight lost generally decreases. So, it has a negative correlation.
  • For "the temperature outside and the number of pool guests": As the temperature outside increases, the number of pool guests usually increases, so it has a positive correlation.
  • For "the number of children assigned to a class and the number of desks": More children means more desks are needed, so it has a positive correlation.
  • For "the price of rice and the number of penguins at the South Pole": There is no logical relationship between these two variables, so no correlation.
  • For "the thickness of the ice on a lake and the likelihood of falling through the ice": As the thickness of the ice increases, the likelihood of falling through the ice decreases. So, it has a negative correlation.

Answer:

  • the number of calories consumed and the amount of weight lost by a person
  • the thickness of the ice on a lake and the likelihood of falling through the ice
