Polychlorinated biphenyl (pcb) is among a group of organic pollutants found in a variety of products, such as coolants, insulating materials, and lubricants in electrical equipment. disposal of items containing less than 50 parts per million (ppm) pcb is generally not regulated. a certain kind of small capacitor contains pcb with a mean of 47.7 ppm and a standard deviation of 7 ppm. the environmental protection agency takes a random sample of 37 of these small capacitors, planning to regulate the disposal of such capacitors if the sample mean amount of pcb is 48.5 ppm or more. find the probability that the disposal of such capacitors will be regulated.

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
