Answer: We reject H₀
We have evidence, to conclude that the mean of cholesterol level in asian inmigrants is not the same as it is in US women
Step-by-step explanation:
Test hypothesis
1. Hypothesis H₀ ⇒ null hypothesis μ₀ = 190
alternative hypothesis μₐ ≠ 190
We see a two tail test at significant value of 5 % with sample of n = 200
α = 0.05 we look for a two tails test the α/2 = 0.025
from z table:
z(c) = + 1.96 on the right and z(c) = - 1.96 on the left
Now for z (s) = ( z - μ₀ )/ ( σ/√n) ⇒ (181,52 - 190) / (40/√200)
z(s) = - ( 8,48* 14,14)/40 z(s) = - 119,91/40 z(s) = - 2.99
z(s) < z(c) - 2.99 < - 1.96
Then z(s) is in the rejection zone we reject H₀
The answer for the last on is 19
Answer:
I think it is 29
Step-by-step explanation:
-6+5((8)-1)=29
Answer:
The Markov chain is a description of the sequence of possible events in which the probability of an event depends only on the state attained in a previous separate event.
Step-by-step explanation:
The relation described by the Markov chain satisfies the following conditions:
1. All states communicate with themselves, that is P₁₁⁰ = 1 ≥ 0
2. There must be symmetry: if i←→j, then j ←→i
3. There must be transitivity. That is if i ←→k and k←→j, then i←→j
The conditions above imply that the communication is an example of an equivalence relation, meaning that it shares the properties with the more familiar relation, that is
i = i , if i = j ,then j = i etc
