I'm answering this question really late, but I need points and I need to practice solving these type of questions lol. Also, hello fellow army! :D

Answer:

This would be the equation: y=1/4*x+b <em>OR </em><em>y=0.5*x+b. </em>Either way works. 0.5 is just 1/4 as a decimal.

Step-by-step explanation:

In this question, you need to find the slope.

The slope-intercept form is y = mx +b. This is what I used to make the equation y=1/4*x+b.

Find the slope.

You would have to find the change in y over the change in x. So change in y divided by the change in x.

Your change in y would be 2. This is because in the y column, the values change by +2.

Your change in x would be 8. This is because in the x column, the values change by adding 8.

So now, we need to divide the change in y over the change in x.

So... 2 divided by 8 equals 0.25.

0.25 as a decimal would be 1/4.

Now we put all of this in slope-intercept form y = mx +b.

The Equation is y=1/4*x+b

Also, stream BTS butter once it releases, haha.

Answer:

y=1/4*x+b

Step-by-step explanation:

The x is a random x point

y is random y point

b is y-intercept

1/4 is the slope

For the hypothesis test H0: μ = 10 against H1: μ >10 and variance known, calculate the Pvalue for each of the following test

Basile [38]

Answer:

a) $p_v =P(Z>2.05)=1-P(z$

b) $p_v =P(Z>-1.84)=1-P(z$

c) $p_v =P(Z>0.4)=1-P(z$

Step-by-step explanation:

Some previous concepts

The p-value is the probability of obtaining the observed results of a test, assuming that the null hypothesis is correct.

A z-test for one mean "is a hypothesis test that attempts to make a claim about the population mean(μ)".

The null hypothesis attempts "to show that no variation exists between variables or that a single variable is no different than its mean"

The alternative hypothesis "is the hypothesis used in hypothesis testing that is contrary to the null hypothesis"

Hypothesis

Null hypothesis: $\mu=10$

Alternative hypothesis: $\mu >10$

If the random variable is distributed like this: $X \sim N(\mu,\sigma)$

We assume that the variance is known so the correct test to apply here is the z test to compare means, the statistic is given by the following formula:

$z_o=\frac{\bar X -\mu}{\sigma}$

Since we have the values for the statistic already calculated we can calculate the p value using the following formulas:

Part a

$p_v =P(Z>2.05)=1-P(z$

And in order to find the answer using excel we can use the following code:

"=1-NORM.DIST(2.05,0,1,TRUE)"

Part b

$p_v =P(Z>-1.84)=1-P(z$

And in order to find the answer using excel we can use the following code:

"=1-NORM.DIST(-1.84,0,1,TRUE)"

Part c

$p_v =P(Z>0.4)=1-P(z$

And in order to find the answer using excel we can use the following code:

"=1-NORM.DIST(0.4,0,1,TRUE)"

Conclusions

If we use a reference value for the significance, let's say $\alpha=0.05$ . For part a the $p_v$ so then we can reject the null hypothesis at this significance level.
