Researchers conducted a study of a program designed to curb street gang gun violence. After implementation of the program in a large city, the researchers examined 90 shootings by members of a particular street gang from that city over the next five years. Of these, only 27 involved shootings of non-gang members. Use a 99% confidence interval to estimate the true proportion of shootings by members of this street gang that involved non-gang members. Interpret the result. The 99% confidence interval is (.). (Round to three decimal places as needed.) Interpret this interval. Choose the correct answer below. O A. There is a 99% probability that the true proportion of shootings by members of this street gang that involved non-gang members is in this interval. B. One can be 99% confident that the true proportion of shootings by members of this street gang that involved non-gang members is outside this interval. C. There is a 99% probability that the true proportion of shootings by members of this street gang that involved non-gang members is outside this interval. D. One can be 99% confident that the true proportion of shootings by members of this street gang that involved non-gang members is in this interval.
