Answer #1

Type I error is the "probability" of rejecting a null hypothesis when it is actually true.

Here you can never calculate the exact probability because you don't know the exact percentages. What you may get as an answer is the region of type I error. That is

Type I error region: "proportion of people who met online and have a satisfactory relationship is greater than the proportion of people who met in person having a satisfactory relationship in the sample when the chances of having a satisfactory relationship in both the situation is same in the population"
