The ability of lizards to recognize their predators via tongue flicks can often mean life or death for lizards. seventeen juvenile common lizards were exposed to the chemical cues of the viper snake. their responses, in number of tongue flicks per 20 minutes, are presented below.421, 370, 727, 659, 268, 727, 217, 574, 489, 710,727, 421, 319, 659, 387, 506, 489a) preliminary data analyses indicate that you can reasonably apply the z-interval procedure. find a 90% confidence interval for the mean number of tongue flicks per 20 minutes for all juvenile common lizards. assume a population standard deviation of 190.0. note: the sum of the data is 8670.confidence interval:

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

answer: the sun

explanation:

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
