The student will calculate the 90% confidence interval for proportion of students in this school that were born in this state.
The student will interpret confidence intervals.
The student will examine the effects that changing conditions has on the confidence interval.
Collect the data
Survey the students in your class, asking them if they were born in this state. Let
= the number that were born in this state.
A
=
B
=
Define the Random Variable
in words.
State the estimated distribution to use.
Find the confidence interval and error bound
Calculate the confidence interval and the error bound.
A
Confidence Interval:
B
Error Bound:
How much area is in both tails (combined)?
=
How much area is in each tail?
=
Fill in the blanks on the graph with the area in each section. Then, fill in the number
line with the upper and lower limits of the confidence interval and the sample proportion.
How large a sample would be needed to ensure that the error for the 90% confidence interval is only 5%? Use the previous data as an estimate for p.
Recalculate the sample size assuming there is no previous data.
Describe the confidence interval
In two to three complete sentences, explain what a Confidence Interval means (in general), as
if you were talking to someone who has not taken statistics.
In one to two complete sentences, explain what this Confidence Interval means for this
particular study.
Using the above information, construct a confidence interval for each given confidence
level given.
Confidence level
EBP / Error Bound
Confidence Interval
50%
80%
95%
99%
What happens to the EBP as the confidence level increases? Does the width of the
confidence interval increase or decrease? Explain why this happens.

A scanning electron microscope (SEM) is ideal for situations requiring high-resolution imaging of surfaces. It is commonly used in materials science, biology, and geology to examine the topography and composition of samples at a nanoscale level. SEM is particularly useful for studying fine details,
Cell division is the process by which a single cell divides into two or more daughter cells. It is a fundamental process in all living organisms and is essential for growth, development, and reproduction. Cell division can occur through either mitosis or meiosis.
life is defined as any system capable of performing functions such as eating, metabolizing,excreting,breathing,moving,Growing,reproducing,and responding to external stimuli.
