1. t-test for the difference between means tor two independent samples with heterogeneity of variance.
2. simple regression.
3. t-test for the difference between means for two related samples.
4. a one sample z-test for proportions for a chi-square goodness of fit).
5. one sample z-test.
6. a two-sample z-test for the difference between proportions for a chi-square test of independence).
7. multiple regression.
8. one-sample t-test.
9. ANOVA
10. Mann-Whitney.
11. chi-square goodness of fit only where a one samplez-test of proportions isn't appropriate).

Answer:

3. t-test for the difference between means for two related samples.      

Step-by-step explanation:

It is given that a professor of UCI wishes to study what really the students remember from their elementary school days and other such stuffs that were very popular at that time.

therefore the professor put forward two test. In one of the test, he put some question from the elementary school and in other he put one question about a pop culture from that time. He used the same sample for both the tests.

So, since the professor involved the same set of students in his experiment for both the tests, so both the samples are related samples.

Therefore, the test uses is a t - test that is used for the difference between the related samples.

Triangles are similar. Round answer to nearest tenth (step by step)
ozzi

Answer:

13.5

Step-by-step explanation:

Similar = alike but not the same

A lot of times in geometry it would mean that they have the same shape, just different size, so first find the ratio:

6/12 = 1/2

27 * 1/2 = 27/2 = 13.5

Here is a scary story for all!! Enjoy!!

The Ghost Man

Once upon a time there was a family, made up of two young ones and their parents. One day, the parents had to go out to do something important. They had to call someone to take care of their children, so they called a lady who was friends with them. Then the lady arrived and the parents left. She made sure the kids ate and then she put them on their bed to sleep. Their house had two floors and the kids were on the second floor upstairs.  Then, she went to sit down on the couch and started to watch tv. She was watching tv when suddenly her phone rang, and she answered the phone. It was an unknown number. She answered it and a creepy voice said, “Have you gone to check on the kids?” When she heard that she automatically hung up. A few minutes later she heard it again, “Have you gone to check on the kids?”. She kept on hearing it for a few times until she started to be a little scared. She called the police as quickly as she could. She told the police that a man who was unknown kept calling her and threatening her. Then the police said that when that man calls again, he will try to locate the man that is calling her. Then the man called again and the police were able to locate the man. A few minutes later, the police called again and he said, “Get out of the house right now because the man that is calling you is on the second floor of your house”. Then the lady remembered that the kids were upstairs so she ran upstairs as fast as she could and it was too late, the kids were gone and there was blood all over their room. The kids were never seen again and lots of police men are still going to look out to find this mysterious man who is going out to get every person he sees. So be careful of what you do because you might hear their cries too.    

Hope you like it!! ;)

Solve the system equations and choose the correct ordered pair <br><br> 3x+2y=12<br> 6x+3y=21
Harrizon [31]

Answer:

(2, 3).

Step-by-step explanation:

3x+2y=12

6x+3y=21    Multiply the first equation by 3 and the second by 2:

9x + 6y = 36

12x + 6y = 42        Subtract:

-3x = -6

x = -6/-3 = 2.

Plug x = 2 into the first equation:

3(2) + 2y = 12

2y = 12 - 3(2)

2y = 6

y = 3.
