Week 7 Project

Hypothesis Testing is the use of statistics to determine the probability that a given claim is true.

The government logs the number of documented births, deaths, marriages and divorces however it is possible to have undocumented cases. In part II of this project, you are going to test claims about total births, deaths, marriages and divorces.

1. • I HAVE TO Complete the summary table for 1. Live Births, 2. Deaths, 3. Marriages, and 4. Divorces highlighting the mean, median, sample/population standard deviation, n = number of states that submitted data for each the data sets.

Summary Table for _________
Mean
Median
Standard Deviation
n (Number of States who submitted Data)

1. Hypothesis Testing

With the information that you gather from the summary tables, test the following (you can use excel when appropriate):

1. I have to Determine if there is sufficient evidence to conclude the average amount of births is over 5000 in the United States and territories at the 0.05 level of significance.
2. I HAVE TO Determine if there is sufficient evidence to conclude the average amount of deaths is equal to 6000 in the United States and territories at the 0.10 level of significance.
3. I HAVE TO Determine if there is sufficient evidence to conclude the average amount of marriages is greater or equal to 2500 in the United States and territories at the .05 level of significance.
4. I HAVE TO Determine if there is sufficient evidence to conclude the average amount of divorces is less than or equal to 4000 in the United States and territories at the 0.10 level of significance.

For each of the tests above, in MY report,I HAVE TO be sure to?

1. Clearly state a null and alternative hypothesis
2. Give the value of the test statistic
3. Report the P-Value
4. Clearly state IS MY conclusion (Reject the Null or Fail to Reject the Null)
5. Explain what MY conclusion means in context of the data.

4.I HAVE TO Make MY OWN Claim (You are completing ONE more Hypothesis Test)

Lastly, propose and conduct your own test of hypothesis.

a) Pick one data set: Births, Deaths, Marriages OR Divorces.

b) Write a claim about the data set.

c) For your claim?

1. Clearly state a null and alternative hypothesis
2. Give the value of the test statistic
3. Report the P-Value
4. Clearly state your conclusion (Reject the Null or Fail to Reject the Null)
5. Explain what your conclusion means in context of the data.
