5. An SPT test was performed at a depth of 4 meters below the ground surface and the following values were obtained: 5-8-10 (each value over a 15 cm depth increment). The efficiency of the SPT hammer was measured as 70%. The unit weight of the soil from 0 to 2 meters is 19.7 kN/m3 , the unit weight of the soil from 2 to 3 meters is 18.6 kN/m3 and the unit weight of the soil from 3 to...

) A sample of 15 graduating students, 15 females and 5 males, was randomly selected. Their GPAs were recorded, and the ranks of these GPAs for the pooled sample are presented below. Test the following hypothesis: H0: There is no difference in GPAs between the genders? Use the Mann-Whitney test. Males Females 11 1 12 2 3 13 14 4 6 5 15 7 8 9 10 Calculated test statistic: Critical value of the test statistic: Decision rule: Decision:
