Global Issues The White Helmets of Syria That has been described as the greatest humanitarian crisis What of the 21st century began in early 2011 with the outbreak of civil war in Syria. For years, this conflict has raged, claiming the lives of hundreds of thousands of people. In addition to the horrible death toll, millions of Syria's citizens have been left homeless or displaced. In fact, the conflict has led to the biggest refugee crisis since the Second World War. Warta simmi Like i Leves cooki 539 dedorq yiripid ei 31 opp JELENT 64 1. D B alos ni bib yo HET PROB Although it may seem that all hope is lost in that tiny part of the world, there is one organization that has been fighting for years to save lives. While it is officially called the Syria Civil Defence or SCD, its members are better known simply as the white helmets. They are volunteers who rush to bombing sites to rescue survivors and give people hope. They often show little regard for their own personal safety, and a great many have been killed or injured attempting to save the lives of others. The white helmets organization was established in rebel-controlled areas that were under constant air attack by government forces. The strategy of the government had been to target not only rebel fighters who opposed them but also the civilians living in the area. Rockets and bombs often destroyed entire neighborhoods, leaving countless innocent people dead and dying. To make matters worse, the government offered no official support since it was the one causing the destruction. Things changed in 2014, however, when the SCD was established. Its white-helmeted members began working tirelessly to pull people from the rubble and give them urgent medical care. It is estimated that they have saved close to 150,000 lives since then. In 2016, the SCD was recognized for its humanitarian efforts when it was nominated for the Nobel Peace Prize. 2.

2. To study the attitude of mother and father towards their daughter participating in the outdoor games, a sample of 200 fathers and 250 mothers was investigated. In these two samples, 120 fathers and 50 mothers preferred their daughter to go for outdoor activities. Can it be concluded at a=0.01 level of significance that the proportion of father is significantly higher than that of mother in preferring their daughters for outdoor activities? 3. A firm has a generous but rather complicated policy concerning end-of-year bonuses for its lower-level managerial personnel. The policy's key factor is a subjective judgment of "contribution to corporate goals." A personnel officer took samples of 24 female and 36 male managers to see whether there was any difference in bonuses, expressed as a percentage of yearly salary. The data are listed here: Gender Bonus Percentage Female 9.2, 7.7, 11.9, 6.2, 9.0, 8.4, 6.9, 7.6, 7.4, 8.0, 9.9, 6.7, 8.4, 9.3, 9.1, 8.7, 9.2, 9.1, 8.4, 9.6, 7.7, 9.0, 9.0, 8.4 10.4, 8.9, 11.7, 12.0, 8.7, 9.4, 9.8, 9.0, 9.2, 9.7, 9.1, 8.8, 7.9, 9.9, 10.0, 10.1, 9.0, 11.4, 8.7, 9.6, 9.2, 9.7, 8.9, 9.2, 9.4, 9.7, 8.9, 9.3, 10.4, 11.9, 9.0, 12.0, 9.6, 9.2, 9.9, 9.0 (1) Is there significant evidence that the mean bonus percentage for males is larger than the mean bonus percentage for females?
