A survey was conducted by an independent price checking company to check an advertiser's claim that it had lower prices than its

Mama L [17]

Answer:

a) critical values ≈ -3.182 and 3.182 shows that there is difference in average prices

b) H0 : μd = 0

Ha : μd ≠ 0

Step-by-step explanation:

a) Determine if there is any significant difference in the average prices

using ∝ = 0.05

and μ( advertiser ) - μ ( competitor ) = μd

test statistic ( t ) = -3.011

df = 3

hence the critical values ( two tailed test ) = -3.182 and 3.182. this shows that there is sufficient evidence to show that there is difference in the average prices

b) state the hypothesis

H0 : μd = 0 ( null )

Alternate hypothesis : Ha : μd ≠ 0

Triangle xyz is similar to triangle xvw. write the congruence statements that must be true.

Lunna [17]

Answer:

∠ Y = ∠ V

∠ Z = ∠ W

$\frac{XY}{XV} =\frac{YZ}{VW} =\frac{XZ}{XW}$

Step-by-step explanation:

It is given that Δ XYZ is similar to Δ XVW.

Since corresponding angles of similar triangles are equal,

∠ X = ∠ X

∠ Y = ∠ V

∠ Z = ∠ W

Also, since corresponding sides of similar triangles are in proportionate,

$\frac{XY}{XV} =\frac{YZ}{VW} =\frac{XZ}{XW}$
