Hypothesis Test on Suicide
Suicide is a serious public health problem that devastates individuals, families, and communities. It is defined as taking one's own life. Suicide behavior is complex. National Vital Statistics Report shows suicide is the 11th leading cause of death among Americans (CDC, 2004). Suicide results from complex interactions between biological, psychological, social, and environmental factors. In this study, numbers of suicide death were examined on the U.S. Mortality Report from 1998 to 2005 (CDC, 2004). The hypothesis suggested whether the yearly mean number of suicide death is more than 26,000. The final statistical analysis indicated that this hypothesis was not rejected because it was below the upper critical value, nor could we support the claim that the mean mortality rate of suicide has increased. This report shall describe A-Team's selection. The report shall discuss type of method used and formulate both a numerical and verbal hypothesis statement regarding our research issue and perform the five-step hypothesis test on data pertaining to our selection. Finally the report shall describe the results of this test and explain how the use of hypothesis test can be used to evaluate solutions to the problem. The findings indicate a substantial increase in homicide rates among young males from 2002 to 2003 and substantial increases in both homicide and suicide rates among males from 2000 to 2003. Research over the past several decades has uncovered a wealth of information on the causes of suicide and the strategies to prevent it. Many studies have identified factors that either increase or reduce the likelihood that a person will attempt or commit suicide. Centers for Disease Control and Prevention and National Center (CDC) used this information to develop and implement prevention programs to reduce the numbers of attempted and completed suicides. The results of the analysis indicate that involvement in risky activities is highly correlated with teen suicide attempts. In particular, teens that use drugs and are sexually active are more likely to attempt suicide. Since these behaviors are most likely engaged in by teens with high future discounting, these results are consistent with the hypothesis that suicide attempts are rational. Unhappiness, as reflected here by dissatisfaction with weight, is at higher risk for 13 attempting suicide. Evidence that most attempts are planned and not just acts of passion provides further support for the rational theory.
