Divide 35423 by 15 and round the answer down to a whole number, then you get 2361. If you subtract 15*2361 from 35423 you get the remainder 8. So answer C is correct.
Q20) c < 82-76
c < 6
Hope this helps
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
i am thinking your answer will be A
