Wow, I thought this video was going to discuss types of sampling methods - like: random, clustering, stacking, etc. and how to calculate sample size! Do you have a video about that? As an internal auditor, I feel it would help me with my samples and sample sizes! Thanks!

The second question is on the, November 2019 2F paper

[@JJ_TheGreat]

1:03 Well - 10/30 = 1/3 of the sample, so extrapolating based on this data, there should be: 1/3 x 195 = 65; therefore, I think 65 of the 195 will want to go to the theme park. This is based on the assumption that the people sampled are similar to the people already sampled in the table - and like the same things in the same proportions - but this is the best guess I have!

[@JJ_TheGreat]

5:17 The answer is: 238, assuming the sample listed in the chart is representative of the sample.

Thank u sir

[@JJ_TheGreat]

7:50 400… And the assumptions are exactly the same as before - it assumes that people within the sample represents what the rest wants…
