A researcher wishes to study whether an antibiotic will inhibit the growth of bacteria in a culture. The researcher inserts the antibiotic into 40 cultures and finds that 20 have reduced growth. A control group of 30 cultures is not given the antibiotic. Of these cultures, 20 have reduced growth. The 90% confidence interval of the difference between the true reduced growth rate of the population of bacteria with the antibiotic and the true reduced growth rate of the bacteria without the antibiotic can be given by a. ) _________ +/- b.) ________ where a.) is the point estimate and b.) is the margin of error.
