The numbers of people in the households are 2, 3, and 10. Assume that samples of size n 2 are randomly selected with replacement from the population of 2, 3, and 10. Construct a probability distribution table that describes the sampling distribution of the proportion of odd numbers when samples of sizes n 2 are randomly selected. Does the mean of the sample sample proportions target the value of the population proportion? Does the sample proportion make a good estimator of the population proportion? Listed below are the nine possible samples s equal the proportion of odd numbers in the population? Do the 2,2 2,3 2,10 3,2 3,3 3,10 10,2 10,3 10.10 Construct the probability distribution table.

Explanation / Answer

Solution:

The number of even numbers in the sample can be 0,1 and 2.
No Even number = (0 Even)
= (3, 3)
= 1
One Even number = (1 Even)
= (2, 3),(3, 2)(3, 10)(10, 3)
= 4
Two Even number = (2 Even)
= (2, 2)(2, 10)(10, 2)(10,10)
= 4
The probability distribution table is,
Sample Proportion Probability
0 1/9
0.5 4/9
1 4/9
   Total = 1
