Sample 1:
Total number of persons in sample is 10.
Out of 10 observations, 8 are white so percentage of white in sample-1 is
White percentage = (8/10) * 100% = 80%
Out of 10 observations, 1 is Hispanic so percentage of Hispanic in sample-1 is
Hispanic percentage = (1/10) * 100% = 10%
Out of 10 observations, 1 is Black so percentage of Black in sample-1 is
Black percentage = (1/10) * 100% = 10%
Sample 2:
Total number of persons in sample is 10.
Out of 10 observations, 7 are white so percentage of white in sample-2 is
White percentage = (7/10) * 100% = 70%
Out of 10 observations, 2 is Hispanic so percentage of Hispanic in sample-2 is
Hispanic percentage = (2/10) * 100% = 20%
Out of 10 observations, 1 is Black so percentage of Black in sample-2 is
Black percentage = (1/10) * 100% = 10%
Sample 3:
Total number of persons in sample is 10.
Out of 10 observations, 6 are white so percentage of white in sample-3 is
White percentage = (6/10) * 100% = 60%
Out of 10 observations, 2 is Hispanic so percentage of Hispanic in sample-3 is
Hispanic percentage = (2/10) * 100% = 20%
Out of 10 observations, 1 is Black so percentage of Black in sample-3 is
Black percentage = (1/10) * 100% = 10%
Out of 10 observations, 1 is Asian so percentage of Asian in sample-3 is
Asian percentage = (1/10) * 100% = 10%
