Question 750341: For a large population of RAM chips, a sample of twenty is taken and a test carried on each of them to see whether they perform correctly. In the test, eight chips are found to perform correctly and the remaining twelve do not perform to specifications.
1. Let p be the proportion of chips performing the specifications in the population of chips, give a point estimate of p which is the yield of the chips.

You can put this solution on YOUR website! For a large population of RAM chips, a sample of twenty is taken and a test carried on each of them to see whether they perform correctly. In the test, eight chips are found to perform correctly and the remaining twelve do not perform to specifications.
1. Let p be the proportion of chips performing the specifications in the population of chips, give a point estimate of p which is the yield of the chips.
------
point estimate = p-hat = 8/20 = 2/5 = 0.4
