Is the mean height for all adult American males between the ages of 18 and 21 now over 6 feet? Let μ represent the population m
SIZIF [17.4K]

Answer:

A. H0: μ = 6 vs. Ha: μ > 6

H0 : µ = 6 vs. Ha : µ > 6

Step-by-step explanation:

Null hypotheses state that there is no difference between a parameter and a specific value.

Alternative hypotheses states a specific difference between a parameter and a specific value.

Null hypotheses is represented as H0

Alternative hypotheses is represented as Ha.

From the question,

The claim is this "Is the mean height for all adult American males between the ages of 18 and 21 now over 6 feet?" The claimed statement represent the Alternative hypotheses.

So, the alternative hypotheses is:

Ha: μ > 6

While the null hypotheses is:

A. 12 + 4x = 6x + 10 – 2x
GalinKa [24]

An equation has infinitely many solutions if it can be manipulated all the way to an identity (i.e. an equality where the right and left hand side are the same). We have:

A) 12+4x=6x+10-2x \iff 12+4x=10+4x \iff 12=10

which is impossible

B) 5x+14-4x=23+x-9 \iff x+14 = x+14

which is an equality

C) x+9-0.8x=5.2x+17-8\iff 0.2x+9=5.2x+9 \iff 0.2x=5.2x\iff x=0

which has a unique solution

D) 4x-2x=20 \iff 2x=20 \iff x=10

which has a unique solution
