Random samples of size n = 200 were selected from a binomial population with p = 0.1. Is it appropriate to use the normal distri
bution to approximate the sampling distribution of p^? Use this result to find the probability. (Round your answer to four decimal places.)
p^ > 0.15
p^ > 0.15

Answer:

Step-by-step explanation:
Given the 2 equations
4x + 3y = 2 → (1)
2x - 3y = 1 → (2)
Adding (1) and (2) term by term will eliminate the y- term, that is
6x = 3 ( divide both sides by 6 )
x = =
Substitute x = into either of the 2 equations and evaluate for y
Substituting into (1)
4( ) + 3y = 2
2 + 3y = 2 ( subtract 2 from both sides )
3y = 0 ⇒ y = 0
Solution is ( , 0 )
