Question 1 In recent times more and more persons on Youtube are creating Patreon pages to generate more income. This however, has caused some of them to lose subscribers because of the fee that needs to be paid monthly. In 2020, it was found that the population proportion of subscribers to unsubscribe from their Youtubers is 0.35. The talks of a global recession, the economic impact of the war between Russia and the Ukraine as well as the observations of a SRS of 110 Youtubers have led Youtube to believe that having a Patreon decreases a Youtubers number of subscribers by a proportion of 0.50. d) Use a 97% confidence interval to estimate the proportion of subscribers who unsubscribed because the Youtuber created a Patreon and the fee was too much. e) Is the interval you created in d) valid?
