It would be 9x+15

g is right above h

If two lines are cut by a transversal and the consecutive exterior angles are supplementary, then the two lines are parallel. Keep in mind you do not need to check every one of these 12 supplementary angles. Just checking any one of them proves the two lines are parallel

The Graduate Management Admission Test (GMAT) is taken by individuals interested in pursuing graduate management education. GMAT
telo118 [61]

Answer:

Null hypothesis: \mu_{Phil} \geq 550

Alternative hypothesis: \mu_{Phil} < 550

Step-by-step explanation:

1) Previous concepts

A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".  

The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".

The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".

2) Solution to the problem

Let X the random variable that represent the score for all test‑takers and the distribution for X is:

X \sim N(\mu =550,\sigma=120)

Let \mu_{Phil} the true mean for the Philippines.

On this case we want to test is \mu_{Phil}

So the correct system of hypothesis for this case would be:

Null hypothesis: \mu_{Phil} \geq 550

Alternative hypothesis: \mu_{Phil}< 550

In order to test we know the population deviation and the sample size n=250. But we need the sample mean and a significance level to test the claim.
