A sample of 16 items from population 1 has a sample variance 5.8 and a sample of 21 items from population 2 has a sample varianc
Nady [450]

Answer:

Reject the null hypothesis.

Step-by-step explanation:

n1 = 16

n2 = 21

S.V1 = 5.8

S.V2 = 2.4

\alpha = 0.05

H_{0} = Population Variance 1 ≤  Population Variance 2

H_{a} = Population Variance 1 >  Population Variance 2

Test statistic value = 5.8 / 2.4 = 2.417

Degrees of freedom is n - 1

15 and 20

Critical value is F_{0.05} = 2.2

2.417 > 2.2

we reject the null hypothesis as the critical value is greater than the test statistic.

A is a finite non-empty set. The domain for relation R is the power set of A.(Recall that the power set of A is the set of all s
siniylev [52]

Answer:

The answer is "Choice D"

Step-by-step explanation:

Determining the information:

For "X \subseteq A " and "Y \subseteq A",  X relates to Y when X and Y has the same cardinality. therefore, R does not have reflective:

For every "X \subseteq A", "X= X" So, X  not proper subset ofX.  So, R does not havereflexive.

R does not have symmetry:

For every "X \subseteq Y" ,then, "Y \subset X"  is not true because X not relate to Y.  So, R is not symmetric.

R does not have antisymmetric:

When X relates to Y and Y is relate to X, then "X \subset Y" and "Y \subset X"\to X=Y

Therefore, R is anti-symmetric.
