Question

At the end of the month, a restaurant manager used the total food sales for the month and the total number of customers for the month to calculate the mean about spent per customer during that month was $12.59. Is this value a statistical or a parameter? Explain.

Answer 1

Answer:

Step-by-step explanation:

It is a parameter, I think. The population is limited to all of the restaurant's customers. Presumably they don't come in to look at the waitresses -- although that might happen. They are there for coffee donuts or a meal, so they are spending money, that's what all of them have in common.

So the population is very confined and very well defined.

The owner is finding a mean. Anything like this is a parameter which defines some aspect of the population.
