Question

To build an interval estimate for the proportion (percentage) of American households who live paycheck-to-paycheck, a random sample 754 full-time workers showed 606 live paycheck-to-paycheck.

19	In the previous question, build a confidence interval such that in 19 out of 20 cases such intervals would capture the actual population proportion of households who live paycheck-to-paycheck is ________.

a	0.794	0.814
b	0.787	0.821
c	0.775	0.832
d	0.756	0.851

Definition Definition Method in statistics by which an observation’s uncertainty can be quantified. The main use of interval estimating is for describing a range that is made by transforming a point estimate by determining the range of values, or interval within which the population parameter is likely to fall. This range helps in measuring its precision.
