Thirty children and forty-five adults were surveyed to determine if children watch, on average, the same amount of television as adults per day. the averages from the study were 3.4 and 2.7 hours per day, respectively. the standard deviations from the study were 2.3 and 1.4 hours per day, respectively. the hypothesis test to use is

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic

perpendicular to x*4 means it's y = -1/4*x+k

so for y = 7 and x = 2

we have 7 = -1/4*2 + k so k = 7.5

so the equation is   y = -1/4x + 7.5
