problem. 82. The median age for US blast currently is 30.9 years, and for US whites it is 42.3 years. Based upon this information give two reasons why the flight median age could be lower than the white median age. All right, possible reasons could be life expectancy. Maybe White's likes fated to live to a much more older Um, yeah, because they lead healthier lifestyles. Maybe it's because they are less prone to having serious diseases. All right, so they have a higher life expectancy or higher median age. All right now, other possible reason could be that, um, it took a Tate's example off black people that are younger people compared to the data sample that we took for white people. Maybe the data sample for white people was fooled with, um, older people. So the medium for white people will be higher than the median age for blood people. All right, question be, does the lower median age for plaques necessarily mean that blackstar younger than whites? Why or why not?

Definitely blacks die younger than whites because there wasn't any areas in Teza something all right, Cristian See, How might it be possible for blacks and whites? It's a diet approximately the same age for the median age for whites to be higher. All right, well, a possible reason for this could be that there was errors in dates of sampling. Again, It's okay.

But use the dates of sampling. The median age is different. Thank you guys
