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

Choose a Data Set.

Go tohttps://www.cdc.gov/nchs/products/nvsr.htm(Links to an external site.)

In the search bar type: Births, Marriages, Divorces, and Deaths

Pick a DataSet and download the PDF document and make note of the volume, number, and date.For example,

Pick the same month/year combination for each data set. For example, choosing September of 2009.

Preliminary Calculations

Put together a summary table for 1. Live Births, 2. Deaths, 3. Marriages, and 4. Divorces highlighting themean, median, sample/population standard deviation, n = number of states that submitted datafor each the data sets.You will have FOUR tables using the list of values of each state, the District of Columbia and Puerto Rico (You could have 52 numbers for each data set. You may have less data numbers if not all states/territories submitted data values.)

1. Hypothesis Testing

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

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.

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.

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.

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 your report, 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 your conclusion (Reject the Null or Fail to Reject the Null)
5. Explain conclusion means in context of the data.

Lastly, propose and conduct test of test of hypothesis

a) Pickonedata set: Births, Deaths, MarriagesORDivorces.

b) claim about the data set.

c) For 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 conclusion (Reject the Null or Fail to Reject the Null)
5. Explain conclusion means in context of the data.
