A sports physician conducted a study to investigate whether there is an association between running experience and the occurrence of a certain sport injury for marathon runners while training for a marathon. Data were collected on a random sample of 51 marathon runners. Each runner from the sample was categorized by running experience (low, medium, high) and whether or not the runner experienced the sport injury while training for a marathon. The conditions for inference were met, and a χ2 test statistic of approximately 8.12 was calculated.

Which of the following describes the p-value of the test?


p-value>0.25

0.10
0.05
0.01
p-value<0.01

Answers

Answer 1

Considering the test statistic for the chi-square distribution, the correct option regarding the p-value of the test is: p-value>0.25

How do we find the p-value for a chi-square distribution?

The p-value is found using a calculator, given two parameters, the test statistic and the number of degrees of freedom.

In this question, the parameters are;

Test statistic = 8.12.

Degrees of freedom = 50

Thus, the sample size = 50 + 1 = 51.

Using an online chi-square calculator, the p-value is of 1, hence the correct option is: p-value>0.25

Answer 2

Answer:

D 0.01< p-value <.05

Explanation:

since 8.12 is our test statistic, we only need to know the degrees of freedom to get our answer. if we were to make a chart of all the catagories we would get 3 rows(low, medium, high) and 2 columns (experienced sport injury while training, and not) In order to find our degrees of freedom we multiply our rows minus 1 and our columns minus 1.

so (3-1)(2-1) and we get 2.

so we can plug these numbers into a calculator and get a p value of .01725, which is in between .01 and .05. Therefore the answer is

D 0.01<p-value<.05

how to say I love you in different words

Answers

Answer:

Honestly it depends what you mean by this.

Explanation:

If you need to tell someone you love them in a different why, let your actions speak along with your words. Compliment them not only on physical things (things they do or how they look) but also on small things they do and say that you really appreciate, but they might not realize. Then of course just doing the little things for them as well will show just as much if not more.

If you need to describe the act of loving someone, you should describe the feelings and responses in the person doing the loving. Not just the joy of being around them, but also caring so much about them you think of them all the time, and the worry that makes you sick. Describe all aspects of it, not just the cliché ones. Any emotion or thought process associated with it can be mentioned.

If you need it for some sort of narrative, describe not only the characters thoughts and feelings (like in the second option) will help. There is a small amount of research you could do if you don't know much about it, but there are things that are tell tale signs of loving someone that you can read in their body language. People who love each other lean towards each other when they are talking. If something funny is said in a big group they will glance at the other person to see what their reaction is. When they talk to the other person or about the other person their pupils will dilate because of reactions in their brain. They will tend to mention the person a lot as well. You can use a lot of these little tidbits to make it clear without straight up tell the readers what is going on.

If the question was straight off of a homework assignment for something, I would pull from all three of those. Hope this helps.
