In constructing a confidence interval estimate for the difference between two population proportions, we:a. pool the population
proportions when the population means are equalb. pool the population proportions when the populations are normally distributedc. always pool the population proportions to construct confidence interval for p1 - p2d. never pool the population proportions to construct confidence interval for p1 - p2e. pool the population proportions when they are equal
In constructing a confidence interval estimate for the difference between two population proportions, we:”b.pool the population proportions when the populations are normally distributed”
Step-by-step explanation:
an interval within which the value of a parameter of a population has a stated probability of occurring.
DescriptionIn statistics, interval estimation is the use of sample data to calculate an interval of possible values of an unknown population parameter; this is in contrast to point estimation, which gives a single value.
