The Research Unit for Cecilion Supermart conducted an experiment to estimate the strength of the carrier bag from the starch-based biofilms made from two different jicamas (sengkuang) of type A and type B. However, the researcher claims that jicama type A produces more strength compared to type B. To support this claim, 10kg weight item was put into 100 carrier bags made from jicama type A and 200 carrier bags made from jicama type B were randomly selected. As a result, 8 bags from jicama type A burst while 12 bags from jicama type B burst. Calculate a 95% confidence interval for the difference in true proportion of the carrier bags which burst between jicama type A and type B. Give comment on the parameter estimate
