Step-by-step explanation:
x^2+3x+xy
Factor form ;
= x (x + 3 + y)
Answer:
Assumptions before conduction hypothesis test are mentioned below in the explanation.
Step-by-step explanation:
As this question is incomplete, and I will try my best to answer this question.
We are asked in this question to write the assumptions that we check before conducting the hypothesis test.
Solution:
Assumptions of hypothesis test:
1. We have to make assumption that all the observations are independent.
2. Secondly, we need to take assumption that, all the parent population of the data reflects normal distribution.
3. Furthermore, we need to assume that experimental error or random error is independently identical and normally distributed with mean "0" and variance of (σ^2).
Above are the assumptions that we should check before conducting hypothesis test.
