Question
It is desired to compare the end-of-term achievements of two faculty members who teach the same course.
The success rate of A was 0.55 and the success rate of B was 0.75. Since the standard tribute of the
40 -
difference between the rates is 0.031, find the confidence limits of the difference between the academic
members' end-of-term success rates with 99% probability.
a) 14%-24% B success rate is lower than A
O B) 12%-30% success rate of A is lower than B
O C) 12%-28% A success rate is lower than B
O D) 14%-28% success rate of A is lower than B
TO) 12%-24% B success rate is lower than A
