Answer:

We accept H₀

Step-by-step explanation:

Normal Distribution

size sample n = 69

sample mean 18.94

standard deviation 8.3

Is a one tailed-test to the left we are traying of find out is we have enough evidence to say that the mean is less than 20 min.

1.-Test hypothesis H₀ ⇒ μ₀ = 20

Alternative hypothesis Hₐ ⇒ μ₀ < 20

2.- Critical value

for α = 0.1 we find from z Table

z(c) = - 1.28

3.-We compute z(s)

z(s) = [ ( μ - μ₀ ) / (σ/√n) ⇒ z(s) = [( 18.94 - 20 )*√69)/8.3]

z(s) = ( -1.06)*8.31/8.3

z(s) = - 1.061

4.- We compare

z(c) and z(s) -1.28 > -1.061

Then z(c) > z(s)

z(s) in inside acceptance region so we accept H₀

Solve for n in the literal equation a(n-2)+5=bn

Helga [31]

Answer:

Answer is below

Step-by-step explanation:

a(n-2)+5=bn

Add -bn to both sides

an-2a+5+(-bn)=bn+(-bn)

an-bn-2a+5=0

add two a to both sides

an−bn−2a+5+(2a)=0+(2a)

an−bn+5=2a

Add -5 to both sides

an−bn+5+(-5)=2a+(-5)

an−bn=2a−5

Factor out our variable

n(a−b)=2a−5

Divide both sides by a-b

n(a-b)/a-b=2a-5/a-b

n=2a-5/a-b

Hope this helps
