Step-by-step explanation:
From the question we are told that
The sample size is n = 26
The mean is 
The standard deviation is 
From the question we are told the confidence level is 95% , hence the level of significance is
=> 
Generally from the normal distribution table the critical value of 
is
Generally the margin of error is mathematically represented as

Answer:
r = 6 cm
Step-by-step explanation:
The volume of a sphere is 288 pi cm tripled . Find the lenght of a radius of a SPHERE.What is the answer and how did you do it?
-------------------
The volume of a sphere of radius r is:
V+=+4%2Api%2Ar%5E3%2F3
It's r cubed, not tripled. meaning r*r*r
-------------------
288pi+=+4%2Api%2Ar%5E3%2F3
864+=+4r%5E3
r%5E3+=+216
r = 6 cm
Answer:
Part A: It tells us the range of time spent surfing the web, and it tells us where the median is on the box plot. The thing that it does not tell us is how many people were in put in the box plot.
B: 60-40= 20
The interquartile range represents where the average scores fell on the box plot.
C: The outlier would change the range and would cause the median to change.
