For the US, the mean monthly internet access spend is $30. A sample of 25 households in Kentucky resulted in a sample mean of $31.50 and a sample standard deviation of 5. You are a researcher for Kentucky's premiere consumer watchdog/advocacy group Daniel Boone Forever. You have been charged with understanding how its citizens' internet bills compare to the national average to ensure Kentucky consumers are being treated fairly. You have to work with only the data in this scenario above as such, what is the most appropriate research question?A. Is there a difference between the internet access spending of Kentuckians as compared to that of the overall US?B. Is there a difference between the internet access spending within the US?C. Is there a difference between the internet access spending amongst Kentuckians?D. Is there a difference between the internet usage of Kentuckians as compared to that of the US overall?

(A) Is there a difference between the internet access spending of Kentuckians as compared to that of the overall US?

Step-by-step explanation:

A research question should capture the objective of the researcher in a given scenerio.

In this instance, the objective of the researcher is to find out if there is a difference between the internet access spending of Kentuckians as compared to that of the overall US.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
