Find the margin of error for the given values of c s and n P

Find the margin of error for the given values of c, s, and n. Please show work

c =.98, s = 2.6, n =11

Solution

Here,

alpha = (1-c)/2 = 0.01

Thus, our critical value for z is

z(alpha/2) = 2.326347874

Thus, as

E = z * s / sqrt(n)

Then

E = 2.326347874*2.6/sqrt(11)

E = 1.823692716 [ANSWER]
