Answer:
G
Step-by-step explanation:
Using the rule of exponents
= 
Consider the left side
=
, then
= n²
Since bases on both sides are equal, equate the exponents
x - y = 2 → G

Answer:
Step-by-step explanation:
In statistical hypothesis testing we use p values. For any test we select significance level alpha as 5% or 1% or 10%
Whenever p < alpha we reject our null hypothesis. Otherwise we accept our null hypothesis.
Hence p should be high to accept null hypothesis
Option A is incorrect
B is correct
C is wrong as p is the probability
D False
Option B is right.
