wo diffe_rent types of in_jection-molding machi_nes are used to form plas_tic parts. Two random samples, each of size 200, are selected from plastic parts produce_d from each machine, respectively. It is discovered that 16(six=teen) def_ective parts are found in the sample from the first machine while only 12 defective parts are found in the sam_ple from the second machine.

Two diffe_rent types of in_jection-molding machi_nes are used to form plas_tic parts. Two
random samples, each of size 200, are selected from plastic parts produce_d from each machine,
respectively. It is discovered that 16(six=teen) def_ective parts are found in the sample from the first machine
while only 12 defective parts are found in the sam_ple from the second machine. Find a 99%
confid_ence interv_al for the true differenc_e of defect_ive proportions between these 2 machines
