the height of six randomly chosen soldiers are inches: 76,70,68,,69,69 and 68. those of 6 randomly chosen sailors are 68,64,65,69,72,64. Discuss the light that these data throw as the suggestions that soldiers are on the average taller than sailors.

To answer this question we need to get the average or rather the mean of the data given above.
The average height f the sailors will be given by :
Average = 1/nx
Where x is the entries and n the total number of entries.The sum of the heights of the sailors is given by :
= (63 + 65 + 68 + 69 + 71 + 72)/6 = 408/6 = 68
The sample average height of the sailors is 68 inches.
The average height of the Soldiers is :
= (61 + 62 + 65 + 66 + 69 + 70 + 71 + 72 + 73)/10 = 609/10 = 60.9
The sample average height of the soldiers is 60.9 years.
From the sample averages we note that the average height of the sailors is higher than the average height of the soldiers hence the Sailors are averagely taller than the soldiers.

The height of soldiers can be predicted as more as they obviously do the tough work. Working on the field, body strength with a subtle brain is their only parameters. They need to be more taller and in shape. The following days says the same. While soldiers average a height of 70 inch while sailors average only 67 inch. 3 inches shorter compared to soldiers. Because their parameters are totally based on their patience and endurance. Shorter peoples are the more resilient ones. So, both mathematically and philosophically soldiers are comparatively taller compared to naval sailors.
