Find the margin of error for the given values of c, sigma, and n. c = 0.90, sigma = 3.7, n = 100 E = ?
Added by Nicholas C.
Step 1
Since c=0.90, we need to find the z-score that corresponds to the area of 0.95 in the standard normal distribution table (since the area in the tails is 0.05/2=0.025 on each side). Using a standard normal distribution table or calculator, we find that the Show more…
