Suppose that a researcher collects some data and produces the following 95% confidence interval for the proportion of Covid-19 cases that are mild or asymptomatic: (0.6988, 0.8518).

Consider the following statements.

(i) If another researcher produces the following 95% confidence interval (0.7288,0.8218) using a new data set, then this new data set was smaller than the original researcher's data set. (ii) The margin of error is 0.153. (iii) If the researcher produced the following new confidence interval (0.7088,0.8418) using the same data, then this new confidence interval has a higher level of confidence. (iv) The percentage of people in the researcher's sample that were mild or asymptomatic was 77.53%.

Determine which of the above statements are True or False, can be donated as true (1), false (2).
