To find how much money the average American family spends to cool their home, 100 Alaskan families are surveyed at random. Of th
e families, 85 said they spend less than $75.00 per month on cooling their homes. Based off that survey, the researcher concluded that the average AMERICAN family spends less than $75.00 per month on cooling their homes. Is this conclusion valid or not valid?
But, in Alaska average daytime summer temperatures range from approximately 55 to 78 °F (12.8 to 25.6 °C); average daytime winter temperatures are about 5 to 30 °F (−15.0 to −1.1 °C). SO, they don't need cooling when compared to rest of the USA. Therefore this will not be valid.
The average per page will be given by: (number of pages)/(time) number of pages=6 pages time=2.5 hours thus average=(6/2.5)=2.4 pages per hour The answer is: 2.4 pages per hour
Yes it is. When you simplify the girls ratio( 12:30 by 6)you'll get 2:5. When you simplify the boys ratio( 16:40 by 8)you'll get 2:5. So it is the same ratio.
