Fairfield homes is developing two parcels near pigeon fork, tennessee. in order to test different advertising approaches, it uses different media to reach potential buyers. the mean annual family income for 20 people making inquiries at the first development is $164,000, with a standard deviation of $42,000. a corresponding sample of 28 people at the second development had a mean of $172,000, with a standard deviation of $30,000. assume the population standard deviations are the same. 1. state the decision rule for .02 significance level: h0: ? 1 = ? 2; h1: ? 1 ? ? 2. (negative amounts should be indicated by a minus sign. round your answers to 3 decimal places.) reject h0 if t is not between and . 2. compute the value of the test statistic. (negative amount should be indicated by a minus sign. round your answer to 2 decimal places.) value of the test statistic 3. at the .02 significance level, can fairfield conclude that the population means are different? h0. fairfield conclude that the population means are different.

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
