Step 1
In Interval scale, the difference between two values are standardized and equal. Most statistical measures are applicable in ratio or interval type of data.
Step 2
Assumptions of Parametric tests:
-Measurement should be ratio or interval,
-Sample should be a random sample,
-Population distribution is normal, and
-Homogeneity of variance
Since, it is one of the assumptions of parametric tests, most researchers still insist on at least interval of measurement as a condition for the use of parametric statistics
Parametric tests are conducted under certain assumptions of the distribution of the data. The distributions are defined by parameters. Hence, the parametric tests are based on the parameters of the underlying distribution.
Answer:
Yes. Most researchers still insist on at least interval of measurement as a condition for the use of parametric statistics.

A poll asked the question, "What do you think is the most important problem facing this country today?" Twenty-five percent of the respondents answered "crime and violence." The margin of sampling error was plus or minus 3 percentage points. Following the convention that the margin of error is based on a \(\displaystyle{95}\%\) confidence interval, find a \(\displaystyle{95}\%\) confidence interval for the percentage of the population that would respond "crime and violence" to the question asked by the pollsters.
Lower limit \(\displaystyle\%\)
Upper limit \(\displaystyle\%\)
