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.
- n≥30n≥30 or normal population
- n(1−p)≥10n(1-p)≥10
- n(pˆ)≥10n(p̂)≥10
- N≥20nN≥20n
- outliers in the data
- σσ is known
- no outliers in the data
- n(1−pˆ)≥10n(1-p̂)≥10
- np≥10np≥10
- 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 the modified boxplot and answer the question below.):
406080100120140160pulse rate after running one minute in bpm4376.5101114.5155[Graphs generated by this script: setBorder(15); initPicture(40,160,-3,6);axes(20,100,1,null,null,1,'off');text([96,-3],"pulse rate after running one minute in bpm");line([43,2],[43,4]); rect([76.5,2],[114.5,4]); line([101,2],[101,4]);line([155,2],[155,4]); line([43,3],[76.5,3]); line([114.5,3],[155,3]);fontsize*=.8;fontfill='blue';text([43,4],'43','above');text([76.5,4],'76.5','above');text([101,4],'101','above');text([114.5,4],'114.5','above');text([155,4],'155','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
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 1)
= bpm
The
(Round endpoints to 1 decimal places and use units exactly as stated in the problem)
( , )
C: Conclusion
- We are % confident that is between bpm and bpm
