Abstract
Life expectancy at birth is the average number of years a newborn infant would live if the health and living conditions at birth remain same throughout its life. Worldwide life expectancy has risen on average by 4 months each year since 1970. This case study will analyze whether there is a difference in life expectancy at birth for male and female population.
Life Expectancy at Birth
Life expectancy at birth is the average number of years a newborn infant would live if the health and living conditions at birth remain same throughout its life. Since 1970, worldwide, on average there is increase of about 4 months in life expectancy at birth. Further, it has been observed that on average life expectancy at birth for female is greater as compared to male. This paper will analyze whether there is a difference in the life expectancy at birth for male and female population.
The data for life expectancy at birth was taken from US Census Bureau. The main benefit that data shows is that from period 1970 to 2005 female life expectancy at birth is greater as compared to male life expectancy at birth. In addition, the data is chosen so that it can be seen actually that living and health conditions are improving day by day and so life expectancy at birth is improving every year.
Figure 1 shows the comparison of US male and female life expectancy at birth for the period 1970 to 2005. It can be seen from figure 1 that for the whole period of 1970 to 2005, female life expectancy at birth was greater than male life expectancy at birth by nearly 7 years. Therefore, it appears that there is a difference in male and female life expectancy at birth. The average male and female life expectancy at birth for the period 1970 to 2005 was about 71.41 years (SD = 2.33), and 78.2 years (SD = 1.53), respectively.
The research question is “Is there a difference in life expectancy at birth for male and female populations?
The null and alternate hypotheses are
(Female and male life expectancy at birth are equal.)
(Female life expectancy at birth is different from male life expectancy at birth.)
The selected significance level, α is 0.05.
As the sample size (n1 + n1 > 30) is large, the selected test is Independent Sample z-test.
At significance level of 0.05, the two-tail critical value of z is ±1.960. Therefore, the decision rule will be
Reject H0 if z > 1.960 or z < -1.960. Otherwise, do not reject H0.
Using MegaStat, the test statistic is
Z = 14.52
P-value < 0.001 (two-tailed)
Since, the value of test statistic 14.52 falls in right-tail rejection region (greater than critical value of 1.96), thus decision is to reject H0. Therefore, there is a difference in life expectancy at birth for male and female populations. This is also confirmed by the p-value ( Read More

### Explain how fate and Oedipus's own essential nnature combine to make him a tragic hero

...? In the playwright Oedipus Rex, Sophocles writes a convincing story regarding the nature of fate and the self destructive search for the truth. Oedipus is a curious individual who attempts to seek the truth over the preservation of the self. This truth manifests itself throughout the play as Oedipus slips further into madness while getting closer to the truth. The very nature of Oedipus causes his grief and the author indicates this by deploying various literary techniques. In his attempts to avoid the fate that he received in his prophecy, Oedipus becomes increasingly delusional.

### All medical care should be free in our society

...All Medical Care Should Be Free In Our Society Nothing in the world is free. People like to believe that good things in life are free for example 'love', but then again some people would argue that no such thing as love exists. Taking a very hard perspective, everything can be seen as a business - an exchange of goods or services. Without such an exchange, there would be minimal justification for someone to give something to another. Therefore I think that even a necessity for human health i.e. medical care should not be free for anyone. Medical care is defined as the "professional treatment for illness or injury" in the Princeton WorldNet Dictionary. The word professional is the key here. In the dictionary it is defined as a person... Medical Care...

### 3 QUESTIONS IN CRIMINAL JUSTICE and deviance

...1. To answer the question as to what are the similarities and the differences between US elite deviance and global elite deviance, it is easy to begin with the similarities. The main similarities appear to be a sense of impunity brought on by having power and a disdain for the rule of law and human rights. Simon (2008: 161) has given many examples of the forms of global deviance, whether in the form of military human rights violations, multinational corporations and the lack of respect for human rights, particularly the human rights of those who belong to developing countries, or acts of violence committed by “death squads” or police units. In the United States, which supposedly has a better set of laws than states such as Colombia or Iran... To answer ...
