Since they are 38 entries we take the middle entries as 19 and 20 and find the average of them.
Median =(68+70)/2 =69
Hence option a is right.
Ответ:
the median age of the presidents at their death is
a. 69
Step-by-step explanation:
age at which 38 U.S. Presidents died.
46 ,58 ,64 ,68 ,73 ,80 ,90 ,49 ,60 ,65 ,70 ,74 ,81 ,93 ,53 ,60 ,66 ,71 ,77 ,83 ,56 ,63 ,67 ,71 ,78 ,85 ,56 ,63 ,67 ,71 ,78 ,88 ,57 ,64 ,67 ,72 ,79, 90
we arrange the data set in ascending order
46,49,53,56,56,57,58,60,60,63,63,64,64,65,66,67,67,67,68,70,71,71,71,72,73,74,77,78,78,79,80,81,83,85,88,90,90,93
median is the central tendency of the data sets
hence, median lies between 68 and 70
hence, median= (68+70)/2
= 69
hence,the median age of the presidents at their death is
a.
69
