Explanation / Answer
The article claims that in United States that majority of people do not have retirement plan or saving like 401K or IRA for retirement. Three out of 5 people in US are not concerned about their retirement.
The evidence is based on the fact that when the people over the age of 30 years of age were asked whether they have IRS or 401K for the retirement. Out of that majority of 65% people said 'no' that they do not have any retirement plan i.e IRS or 401 K , 30% said 'yes' and 5% said they 'do not know' about this. The result has an margin error of +3 or -3 percent.
Since there is only margin error of +3 or -3 percent so the evidence are good which claimed that majority of people of 30 years of age do not have any retirement plan i.e IRS or 401K.
Non sampling bias can be created by the ordering of questions, introduction of polls or questions phrasing. If the poll was taken just after the news event which could temporarily affect the views of the people. Also the bias in the result can be introduced by whether the respondents were able to understand the questions and were honest in their answers.
