Let u represent the average difference in time (actual time - estimated time) it took to complete the problem for all students. She would like to investigate whether there will be convincing statistical evidence that the students overestimate the time it took to complete the problem, on average. Which of the following is the correct hypotheses for this test?

Question

Transcribed Image Text:12. A study conducted by a professor at Waynesburg University investigated
whether time perception is impaired when completing the last example problem
just prior to the start of fall break. The professor timed how long it took to
complete the last example problem (in seconds), then asked a random sample of
10 students to estimate how long it took to complete the problem (in seconds).
Let U represent the average difference in time (actual time - estimated time) it took to
complete the problem for all students. She would like to investigate whether there will be
convincing statistical evidence that the students overestimate the time it took to complete
the problem, on average. Which of the following is the correct hypotheses for this test?
(A) Ho : µ = 0 and Ha : µ 0
(B) Ho : µ = 0 and Ha : µ > 0
%3D
(C) Ho : µ = 0 and Ha : µ < 0
(D) Ho : µ > 0 and Ha : µ < 0
(E) Ho : µ < 0 and Ha : µ = 0
