The numbers of people in the households are 3,5, and 10. Assume that samples of sice n 2 are randomly selected with replacement from the population of 3,5, and 10 Construct a probability distribution table that descibes the sampling distribution of the proportion of ods numbers whan samgles of sizes n-2 aro randomly sample proportions target the value of the population proportion? Does the samle proportion make a good estimator selected Does the mean of the sample proportions equal the proportion of odd numbers in the population? Do the of the population proportion?

Explanation / Answer

from above as total 9 samples are there therefore each sample has probability =1/9

there is one sample where 0 odd number are there which is 10,10 ;

hence for sample proportion=0 ; probability =1/9

for sample proportion =0.5 ; probability=4/9 (3,10 ; 5,10 ; 10,3 ; 10,5))

and for sample proportion =1 ; probability=4/9

sample proportion probability 0 1/9 0.5 4/9 1 4/9
