Car manufacturers are interested in whether there is a relationship between the size of car an individual drives and the number of people in the driver's family (that is, whether car size and family size are independent). To test this, suppose that 797 car owners were randomly surveyed with the following results. Conduct a test for independence at the 5% level. Family Size Sub & Compact Mid-size Full-size Van & Truck
1 19 34 40 36
2 21 49 70 81
3-4 19 49 101 89
5+ 20 30 71 69

Required:
a. What are the degrees of freedom?
b. What is the test statistic? (Round your answer to two decimal places.)
c. What is the p-value? (Round your answer to four decimal places.)

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
