Explanation / Answer

Solution :-

Here you have been providede a good data that needs to examined sattistically.

You need to prepare a word file, where you are needed to provide all your observations that you get after working out the given problems.

1. Once you are done by creating a word document with your name, in order to work with the Research Article you need to State the basic bibliographic information for the article.

That will consist of Name of Author, Title of Article, Title of Journal, (Title are usually given on the first page of the article), Volume and issue number, Date of publication and Page numbers.

2. Did the author use critical values, p-values, or both?

Critical values for a test of hypothesis depend upon a test statistic, which is specific to the type of test, and the significance level, , which defines the sensitivity of the test. A value of = 0.05 implies that the null hypothesis is rejected 5 % of the time when it is in fact true. The choice of is somewhat arbitrary, although in practice values of 0.1, 0.05, and 0.01 are common. Critical values are essentially cut-off values that define regions where the test statistic is unlikely to lie; for example, a region where the critical value is exceeded with probability if the null hypothesis is true. The null hypothesis is rejected if the test statistic lies within this region which is often referred to as the rejection region(s)

Another quantitative measure for reporting the result of a test of hypothesis is the p-value. The p-value is the probability of the test statistic being at least as extreme as the one observed given that the null hypothesis is true. A small p-value is an indication that the null hypothesis is false.

(This is what you can look into the article that you have choosen there will be a clear mention of what test is being performed, usually articles show both the tests.)

3. State either a null hypothesis or a research question from the article.

You can read the conclusion part of your article to find the answer for this, because there usually you get the final result of the research acticle.

4. State one conclusion from the article.

Usually at the observation part, the question being raised from the beigining is answered so I hope you can find the final conclusion from there or you can also write down your own conclusion from the article.

5. Refer to the Class Summary Number of Siblings data. Enter the data in C1 label it Siblings. Choose stat, basic statistics, and 1-sample T. Click the Sample in Columns button and enter C1. Click options and enter 95.0 as the Confidence level and not equal. Click okay twice. Copy and paste your One-sample T results into your Word document. Save your worksheet.

Here, you are given clear steps that you need to follow in order to work with you T-intervals working with the Class Summary Number of Siblings data (that you might be provided with)

6. Refer to exercise #11 on p. 480. State the null and alternative hypotheses.

Elementary Statistics 9th edition, by Neil Weiss Pearson/Addison Wesley.

Now you preform Significance Tests about Proportions, you are given with information, where you need to refer with in point 6. Also you need to state the null and alternate hypothesis.

H0 : The null hypothesis states that a population parameter is equal to a value. The null hypothesis is often an initial claim that researchers specify using previous research or knowledge.

H1 or Ha :The alternative hypothesis states that the population parameter is different than the value of the population parameter in the null hypothesis. The alternative hypothesis is what you might believe to be true or hope to prove true.

7. Next we are going to complete the hypothesis test. Choose stat, basic statistics, and 1-proportion. Click summarized data. Enter 578 for the number of events and 2512 for the number of trials. Check the box for perform hypothesis test and enter 0.25 for the hypothesized proportion. Click options and enter 95 as the confidence level and less than for the alternative. Check the box for use test and interval based on a normal distribution. Click OK twice. Copy the results into your Word document.

Here you are provided with the steps that needs to be followed in order to test hypothesis.

8. Based on the p-value, what is your conclusion?

When you are done with all your hypothesis testing, you will get the final conclusion, that is by compairing the answer you worked out and the confidence level you have choosen.

If your P value is less than the chosen significance level then you reject the null hypothesis i.e. accept that your sample gives reasonable evidence to support the alternative hypothesis.

I hope this will help you to understand the question better. Thank You.
