I am quite surprised to see how Ashu misunderstood the general rules of Statistics. Your 5 % (per cent) statement is already your assumed conclusion even without doing the preliminary analysis of the data. It means you are writing the conclusion to swing the public of this forum to like you thinkingn that this public is not educated as much as you are. How deep you have studied the statistics? Did you only take fundamentals of statistics in your undergraduate or have you alsotaken some advance courses on statistics, I am just wondering !! Probably you didn't understood Statistics correctly during your studies. Little knowledge is a dangerous thing, as somebody said in the past... (I tried to find the source, but haven't got success in that, So Prem D ji do not come after me telling that I am plagiarist!!!). What if it turns out that only less than 5 per cent of the public the like you? Think about it. I am sure you didn't transform the data to get bell-shaped curve and based your inferences forgetting to transform back!!!! Be Careful. I hate to see people manipulating the statistical inferences..it often happens a lot though, even by some professors of statistics!!
