Question

For every 100,000 baby boys born in the US in 2018, the Office of National Statistics (ONS) used current mortality rates to predict the number that would die at each age. According to the ONS, the data is skewed to the left - with most males born in 2018 predicted to die in their eighties and comparatively few predicted to die as babies. The two measures of center for the life expectancy of US males born in the 2018 are 79 years and 82 years.

Which number best represents the median life expectancy for US males born in 2018 and which number best represents the mean?


1- 79 years is the median and 82 years is the mean

2- 79 years is the mean and 82 years is the median.

Answer 1

2 - 79 years is the mean and 82 years is the median.

Explanation:

In a given skewed to the left graph, to be able to distinguish between the two measures of center for this expectancy study, the mean is relatively smaller than the median in a skewed left distribution curve.

In this study, The two measures of center for the life expectancy of US males born in the 2018 are 79 years and 82 years. Thus, 79 years is the mean and 82 years is the median.
