ACTIVITY 1

How large should a sample be? 1. 90% confidence level, margin of error (E) = 3.7, o = 7.5 2. 97%% confidence level, E = 5.1, o = 12 3. 95%% confidence level, E = 7, o = 25 4. 95%% confidence level, E = 0.15, p = 0.25 5. 99% confidence level, E = 0.2, p = 0.55Compute the interval estimate of the following: 1. Confidence level = 98%%, n = 50, x = 36, 0 = 21 2. Confidence level = 90%, n = 36, x = 75, o = 11.5
