Expert Solution
Levene's test is used to test different sample variance's equality i.e; homoscedasticity. The test assumes that the variances are equal among different sample groups. It is similar to one way ANOVA.The levene test is define
H0: σ21=σ22=…=σ2k
Ha: σ2i≠σ2j for at least one pair (i,j).
The levene's test statistics is defined for a given variable Y
with sample size N of subgroup k each having Ni sample size and
example is provided in picture attached with this answer.

Give an example of how annealing is used in an engineering
application. Also, briefly explain how and why the mechanical
properties—for a metal—of yield strength, ductility, hardness,
Young’s modulus, ultimate tensile strength, and toughness are
different for a cold worked metal vs a metal that has been annealed
at a relatively high temperature for a relatively long time (must
talk about grain size).
