A tech company develops a navigation app for smartphones that can compute the usual distance it takes to get from one location to another. The company collects location data from 100 smartphones to determine how long it takes to drive from Cleveland, Ohio, to Detroit, Michigan. The company finds that it takes an average of 2.78 hours to drive this distance with a standard deviation of 0.06. The driving times appear to be normally distributed.

This company wants to provide an estimate of a range of driving times that include the driving times for 95% of users.

What would this range be?

a) 0 to 2.66 hours
b) 2.60 to 2.96 hours
c) 1.82 to 3.74 hours
d) 2.66 to 2.90 hours

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
