Question: Calculate the standard error when: a. = 9.8 and n = 12. b. = 9.8 and n = 25. c. = 9.8

Calculate the standard error when:

a. σ = 9.8 and n = 12.

b. σ = 9.8 and n = 25.

c. σ = 9.8 and n = 180.

d. σ = 4.2 and n = 12.

e. σ = 12.9 and n = 25.

f. σ = 1.3 and n = 180.

g. Compare the standard errors in 16a–16f. What happens to the standard error as σ increases?

h. Compare the standard errors in 16a–16f. What happens to the standard error as n increases?
