Answer:
If two triangles Δ RST and Δ XYZ are similar, then corresponding angles are equal and their corresponding sides are proportional.
So here ∠R=∠X, ∠S=∠T and ∠T=∠Z
From the question, we know the population standard deviation, σ = 1.63, the sample standard deviation, s = 3.07, the sample mean,

and the sample size, n = 38.
The question illustrates a hypothesis chi-square test of variance.
