It is believed that the average height of General Engineering (GE) students is 1.72 meters, which is 0.07 meters higher than Development Communication (DC) students with standard deviations of 0.34 meters and 0.30 meters respectively. An instructor verified this fact by obtaining 49 GE students and 36 DC students, having the average height of 1.75 meters and 1.66 meters. Is there an evidence that the instructor can circumvent the fact at 5% level of significance? 1. What is the level of significance of the problem? 2. What is the critical value of the problem?
