When comparing correlation, focus on the MAGNITUDE of r:
Compare |0.828| with |-0.879|. Which magnitue is greater? The r value with greater magnitude represents the stronger correlation.
Answer:
Sample
Step-by-step explanation:
Given that television station XYZ wants to know the proportion of TV owners in Virginia who watch the station’s new program at least once a week. The station asks a group of 1000 TV owners in Virginia if they watch the program at least once a week. 250 of the TV owners surveyed indicated they did watch the program at least once a week.
Here the population is the set of all TV owners in Virginia
The group of 1000 TV owners asked about their opinion is the sample
Answer is it is a sample.
Note: The main difference between a population and a sample is that the population includes all the elements of the set while sample includes only a subset of the whole set.
It is proportional. If you consider the 288 miles on 12 gallons you need to find how many are driving on one gallon so divide 288 by 12 and you get 24 then multiply 24 by 10 to get 240 miles on 10 gallons of fuel.
