What inferential statistics question might be answered by determining the number of such computers in a sample of size 800 that need warranty service?
O Does the sample provide compelling evidence for concluding that more than 10% of all such computers need warranty service?
O Can we conclude that the population will have the same percentage of warranty service as the sample needed?
O Suppose that 120 of the 800 sampled needed warranty service. How confident can we be that the proportion of sampled computers needing warranty service is between 8 and 22 ?
O Suppose that 120 of the 800 sampled needed warranty service. How confident can we be that the proportion of all such computers needing warranty service is between 0.08 and 0.22
O Does the population provide compelling evidence for concluding that more than 10% of the sample computers need warranty service?
