Please, help me solve the following:

A movie goer observes that millennials watch movies 'om their devices instead of going to the cinema. To determine the mean number of visits to the cinema among young adults in his subdivision, the movie goer divided the subdivision into two blocks that resulted to 300 households in Block I and 200 households in Block 2. Then, he used SRS to select 4 and 3 households in Blocks 1 and 2, respectively. He then interviewed a randomly selected millennial from each of the sampled household and ask for the number of times the respondent visited the cinema. The table below summarizes the result of this question. where M denotes the number of young adults in household 5", 5 denote the number of visits to the cinema ofthe sampled young adult in household; You were requested to advise the movie goes. a. Did the moviegoer implement an m sample design? Why or why not? b. Determine the selection equation for each stratum. c. Calculate the weights suitable for computing the mean. (5. Compute the weighted and unweighted mean. Compare. Which is appropriate in this situation
