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, n = 11, so using the t distribution,

df = n - 1 = 10

Thus, at 98% confidence, using table/technology,

t = 2.763769458

Thus,

E = t s / sqrt(n) = 2.763769458*2.6/sqrt(11)

= 2.166600398 [ANSWER]
