1. The Mathematical Anxiety Rating Scale (MARS) measures an individuals level of mathematical anxiety on a scale from 25 ( no anxiety) to 100 ( highest anxiety) . A group of researcher administered the MARS to 50 students. One of the objectives of the study was to determine if there is a difference between levels of mathematical anxiety experienced by male and female computer science students. GENDER S n Male 34.8 10.6 24 Female 47.2 12.4 26 - At a = 0.05 level of significance , is there evidence of a difference in the mean mathematical anxiety experienced by male and female computer science students? - 2. A survey found that the average hotel room rate in Luzon is P4,300 and the average room rate in Mindanao is P3,850. Assume that the data were obtained from two samples of 75 hotels in Luzon and 80 hotels in Mindanao and the standard deviations were P 385 and P 315 , respectively. At a = 0.05 , can it be concluded that there is significant difference in the rates
