Life Expectancy Life expectancy for all the different countries in the world ranges from a low of only 45.6 years (in Sierra Leone) to a high of 83.8 years (in Hong Kong). Life expectancies are clustered at the high end, with about half of all the countries having a life expectancy between about 74 and the maximum of 83.8 . A few countries, such as Sierra Leone, have a very low life expectancy. The full dataset is in AllCountries. I From the information given, estimate the median of the life expectancies. (b) Found your answer to the nearest integer. Redian = i

To estimate the median life expectancy from the information provided, we can focus on the clustering of data. Given that about half of the countries have a life expectancy between 74 and 83.8, we can reasonably derive that the median is around the midpoint of this range. So, calculating the average of 74 and 83.8 gives us approximately 78.9, which rounded to the nearest integer results in a median life expectancy of about 79 years. Now, let’s think about the significance of that figure! A median life expectancy of 79 years reflects not only healthcare advancements and living conditions but also cultural practices and lifestyle choices. Countries at the high end often have robust healthcare systems, emphasizing preventive care and healthier diets, which contribute significantly to this higher life expectancy.
