To the researcher, the population of interest is the <em><u>men</u></em><em> </em>in the village, the relevant population data are the <em><u>height of men</u></em> in the village, and the population parameter of interest is the <em><u>mean height of men</u></em>.
It is also provided that there are 590 men in the village, and the sum of their heights is 3,410.2 feet.
Compute the average height as follows:
Thus, the population mean height of men in the village is 5.78 feet.
It is given that the researcher measured the heights of 18 village men and calculated the average to estimate the average height of all the village men.
The sample for his estimation is <em><u>18 men</u></em>, the relevant sample data are the <em><u>heights of the 18 men</u></em>, and the sample statistic is the <em><u>sample mean height</u></em>.
It is also given that the sum of the heights of the 18 village men is 104.4 feet.
Compute the average height of the 18 men as follows:
Thus, the sample mean height of men in the village is 7.8 feet.
