a. What is the range of possible sampling error if a random sample of size

nequals=6

is selected from the​ population?The possible sampling error ranges from

negative 297.50−297.50

to

254.16254.16.

​(Round to two decimal places as needed. Use ascending​ order.)

b. What is the range of possible sampling error if a random sample of size

nequals=10

is​ selected? The possible sampling error ranges from

negative 243.67−243.67

to

218.83218.83.

​(Round to two decimal places as needed. Use ascending​ order.)

Compare your answers to parts a and b and explain why the difference exists.

A.

As the sample size​ increases, the range of sampling error increases.

B.

As the sample size​ increases, the sampling error becomes more positive.

C.

Sample size has no effect on the sampling error.

D.

As the sample size​ increases, the sampling error becomes more negative.

E.

As the sample size​ increases, the range of sampling error decreases.
