Answer: The number of air conditioners sold per day in a city and the daily temperature

Step-by-step explanation:

We know that if there is a causal relationship between two variables then one variable is responsible for causing the other variable.

  • the number of hats sold and the number of mittens sold in a city.

there is no causal relationship between the variables since both are independent variables.

  • the amount of butter and the amount of bread consumed by a family
    .

there is no causal relationship between the variables since both are independent variables.

  • the number of notebooks sold and the number of pens sold in a stationery store
