Answer:
A) Status of Rate structure
B) Rate of usage of Electricity
C) Double blind
D) Neither
Step-by-step explanation:
A) The Explanatory variable is the Status of Rate structure during peak hours
B) The response Variable
The response variable in this experiment is the rate of usage of Electricity
( i.e. via meter readings )
C) The experiment can be considered a double -blind because the participants do not know the group they are assigned to ( either standard rate or time-of-day rate structure) but can only read their meters while the technician does not know what rate structure the participants where assigned to or what meter was assigned to each group
D) The experiment Did not use matched blocks or matched pairs
Because the type of cat food is irrelevant we can add them together:
25 + 35 = 60 kg of cat food
1 kg = 1,000 grams
60 kg = 60,000 grams
60,000 / 300 gram pockets = 200 pockets
He will make 200 pockets (with 60kg of food)
