The type of variable required is Qualitative with two possible outcomes.
What is a confidence interval?
An estimate's level of uncertainty is expressed by a range of values known as a confidence interval.
<em>Keeping in mind</em>, the z-score and other data's decimal places should be preserved when generating the confidence interval's upper and lower bounds. The responses will be accurate and round-off errors will be prevented.
<em>Also</em>, the confidence interval's boundaries are expressed in percents. The maximum value of 0.8740, for instance, is 87.4% in decimal notation.
Make sure to specify the confidence level, the percentage of the population that the confidence interval actually captures, and the bounds expressed in percentages when expressing the meaning of the confidence interval.
Hence, the type of variable required to construct a confidence interval for a population proportion is Qualitative with 2 possible outcomes.
