Answer:

Look bucko this story will help u, make sure to read it all!

Step-by-step explanation:

She tried to explain that love wasn't like pie. There wasn't a set number of slices to be given out. There wasn't less to be given to one person if you wanted to give more to another. That after a set amount was given out it would all disappear. She tried to explain this, but it fell on deaf ears.

Cake or pie? I can tell a lot about you by which one you pick. It may seem silly, but cake people and pie people are really different. I know which one I hope you are, but that's not for me to decide. So, what is it? Cake or pie?

It was a concerning development that he couldn't get out of his mind. He'd had many friends throughout his early years and had fond memories of playing with them, but he couldn't understand how it had all stopped. There was some point as he grew up that he played with each of his friends for the very last time, and he had no idea that it would be the last.

She nervously peered over the edge. She understood in her mind that the view was supposed to be beautiful, but all she felt was fear. There had always been something about heights that disturbed her, and now she could feel the full force of this unease. She reluctantly crept a little closer with the encouragement of her friends as the fear continued to build. She couldn't help but feel that something horrible was about to happen.

I'm heading back to Colorado tomorrow after being down in Santa Barbara over the weekend for the festival there. I will be making October plans once there and will try to arrange so I'm back here for the birthday if possible. I'll let you know as soon as I know the doctor's appointment schedule and my flight plans.

She reached her goal, exhausted. Even more chilling to her was that the euphoria that she thought she'd feel upon reaching it wasn't there. Something wasn't right. Was this the only feeling she'd have for over five years of hard work?

At that moment he had a thought that he'd never imagine he'd consider. "I could just cheat," he thought, "and that would solve the problem." He tried to move on from the thought but it was persistent. It didn't want to go away and, if he was honest with himself, he didn't want it to.

You can decide what you want to do in life, but I suggest doing something that creates. Something that leaves a tangible thing once you're done. That way even after you're gone, you will still live on in the things you created.

He looked at the sand. Picking up a handful, he wondered how many grains were in his hand. Hundreds of thousands? "Not enough," the said under his breath. I need more.

There once lived an old man and an old woman who were peasants and had to work hard to earn their daily bread. The old man used to go to fix fences and do other odd jobs for the farmers around, and while he was gone the old woman, his wife, did the work of the house and worked in their own little plot of land.

The national mean annual salary for a school administrator is $90,00 a year (The Cincinnati Enquirer, April 7, 2012). A school o

timurjin [86]

Answer:

a) Null hypothesis: $\mu = 90000$

Alternative hypothesis: $\mu \neq 90000$

b) $p_v =2*P(t_{(24)}$

c) If we compare the p value and the significance level given $\alpha=0.05$ we see that $p_v$ so we can conclude that we have enough evidence to reject the null hypothesis, so we can conclude that the true mean for the salary differs from 9000 at 5% of significance.

Step-by-step explanation:

1) Data given and notation

77600 ,76000 ,90700 ,97200 ,90700 ,101800 ,78700 ,81300 ,84200 ,97600 ,

77500 ,75700 ,89400 ,84300 ,78700 ,84600 ,87700 ,103400 ,83800 ,101300

94700 ,69200 ,95400 ,61500 ,68800

We can calculate the sample mean and deviation with the following formulas:

$\bar X =\frac{\sum_{i=1}^n X_i}{n}$

$s=\sqrt{\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}}$

The values obtained are:

$\bar X=85272$ represent the mean annual salary for the sample

$s=11039.23$ represent the sample standard deviation for the sample

$n=25$ sample size

$\mu_o =90000$ represent the value that we want to test

$\alpha=0.05$ represent the significance level for the hypothesis test.

t would represent the statistic (variable of interest)

$p_v$ represent the p value for the test (variable of interest)

Part a: State the null and alternative hypotheses.

We need to conduct a hypothesis in order to check if the mean salary differs from 90000, the system of hypothesis would be:

Null hypothesis: $\mu = 90000$

Alternative hypothesis: $\mu \neq 90000$

If we analyze the size for the sample is < 30 and we don't know the population deviation so is better apply a t test to compare the actual mean to the reference value, and the statistic is given by:

$t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}$ (1)

t-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".

Part b: Calculate the statistic

We can replace in formula (1) the info given like this:

$t=\frac{85272-90000}{\frac{11039.23}{\sqrt{25}}}=-2.141$

P-value

The first step is calculate the degrees of freedom, on this case:

$df=n-1=25-1=24$

Since is a two sided test the p value would be:

$p_v =2*P(t_{(24)}$

Part c: Conclusion

If we compare the p value and the significance level given $\alpha=0.05$ we see that $p_v$ so we can conclude that we have enough evidence to reject the null hypothesis, so we can conclude that the true mean for the salary differs from 9000 at 5% of significance.

A teacher has a bag of candy. If she gives every student in her class 4 pieces of candy, she is left with 48 pieces of candy. Ho

yawa3891 [41]

Well you can't actually find a number, but you can make an equation.
lets call the bag of candy x, and the number of students in the teachers class S.

she gives every student in her class 4 pieces, so to find that amount, we have to multiply the number of students in her class by 4, the pieces of candy. 4S

afterwards she has 48 pieces, which is the endpoint, x is the starting point because that's the amount of candy the teacher started with.

so your equation is x-4S=48, but the thing is, the question is looking for the amount of students she gave candy to, so we have to isolate S, or in easier words; put S on one side, and the numbers on the other.

so the equation is S=1/4x-12
