P: Parameter

What is the correct parameter symbol for this problem?

What is the wording of the parameter in the context of this problem?

A: Assumptions

Since information was collected from each object, what conditions do we need to check? Check all that apply.

np≥10np≥10
σσ is known
N≥20nN≥20n
n≥30n≥30 or normal population
n(1−pˆ)≥10n(1-p̂)≥10
n(pˆ)≥10n(p̂)≥10
outliers in the data
n(1−p)≥10n(1-p)≥10
no outliers in the data
σσ is unknown

Check those assumptions:

1. Is the value of σσ known?

2. Given the following modified boxplot (If using a screenreader, use technology to generate a boxplot, then answer the question below):

7580859095100percentage of woman receiving prenatal care in percent79.2387.7393.396.235100[Graphs generated by this script: setBorder(15); initPicture(75,100,-3,6);axes(5,100,1,null,null,1,'off');text([85.385,-3],"percentage of woman receiving prenatal care in percent");line([79.23,2],[79.23,4]); rect([87.73,2],[96.235,4]); line([93.3,2],[93.3,4]);line([100,2],[100,4]); line([79.23,3],[87.73,3]); line([96.235,3],[100,3]);fontsize*=.8;fontfill='blue';text([79.23,4],'79.23','above');text([87.73,4],'87.73','above');text([93.3,4],'93.3','above');text([96.235,4],'96.235','above');text([100,4],'100','above');fontfill='black';fontsize*=1.25;]

How can we identify outliers on a modified boxplot?

Are there any outliers?

3. nn= which is

Is it reasonable to assume the population is normally distributed?

N: Name the procedure

The conditions are met to use a .

I: Interval and point estimate

The symbol and value of the point estimate are as follows:

     (Round answer to 3)

            =  percent

The interval estimate for            is as follows:

(Round endpoints to 3 decimal places and use units exactly as stated in the problem)
