This is the topic given to me to write up a statistical report on this. Further I tried my own ideas to make a write up on this topic which need to be discussed for clarity.
Problem:
Gold rate change is happening because of some random chances not any significant causes involved on it.
I want to prove or disprove the above statement. Hence I made the statement very specific as the gold rate fluctuation from 2008 to 2009 is happened because of some random chances not any significant causes involved on it.
Data
The below data is the gold rate per ounce in ABCD country.
Data source: http://www.gold.org/deliver.php?file=/value/stats/statistics/xls/web_daily.xls
Methodology
1) Student ‘t test
2) Auto correlation
Analysis
Hypothesis:
Gold rate fluctuation from 2008 to 2009 is happened because of some random chances not any significant causes involved on it.
Test:
As the T – value is greater than t –critical value the fluctuations because of some assignable causes not just a random chances.
Result:
Hence our hypothesis is not true. There is some specific reasons beyond this rate increment of Gold which is need to be further investigation.
Result:
Hence our hypothesis is not true. There is some specific reasons beyond this rate increment of Gold which is need to be further investigation.
