Question

Suppose that a student in this class uses their personalized class data set to find the following confidence interval for the proportion of students in this class who travel more than 5 km to school: (.171, .243). Consider the following statements. (i) If that same student used the same data set to produce the following confidence interval for the proportion of students who travel more than 5km to school, (.184, .230), then this new confidence interval must have a higher level of confidence than the interval (.171, .243). (ii) The proportion of students in that same student's personalized class data set who travel more than 5km to school might not be in the interval (.171, .243). (iii) The true proportion of students in this class who travel more than 5km to school must be in the interval (.171, .243). Determine which of the above statements are true (1) or false (2). So, for example, if you think that the answers, in the above order, are True,False,False, then you would enter '1,2,2' into the answer box below (without the quotes).

Answer 1

The 1st statement is true and 3rd one is also true, but 2nd one is not true. So correct order is 1,2,1.
