Ppose that a random sample of 204 twenty-year-old men is selected from a population and that their heights and weights are recorded. A regression of weight on height yields ModifyingAbove Weight with caret equals (negative 101.3982 )+ 4.0188timesHeight, Upper R squared = 0.826, SER = 10.4040 (2.1930 ) (0.3162) where Weight is measured in pounds and Height is measured in inches. A man has a late growth spurt and grows 1.5300 inches over the course of a year. Construct a confidence interval of 99% for the person's weight gain. The 99% confidence interval for the person's weight gain is ( nothing, nothing) (in pounds). (Round your responses to two decimal places.)

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
