Question
Please show work!!!! Thanks!
Listed below are the lead concentrations (in mg/g) measured in different samples of a medicine. What do the results suggest about the safety of this medicine? What do the decimal values of the listed amounts suggest about the precision of the measurements? 12 13 18.5 9 145 6 19 12 13.5 21 The mean of the data set is mg/g (Type an integer or a decimal. Do not round.) The midrange of the data set is mg/g (Type an integer or a decimal. Do not round.) The median of the data set is mglg (Type an integer or a decimal. Do not round.) What is the mode of the data set? Select the correct choice below and, if necessary, fill in the answer box within your choice 0 A. The mode(s) of the data set is (are) (Type an integer or a decimal. Do not round. Use a comma to separate answers as needed.) O B. There is no mode What do the results suggest about the safety of this medicine? Choose the correct answer below. OA. The lead content in this medicine is not harmful to a patient. O B. The lead content in this medicine is lethal to a patient. ° C. The lead content in this medicine is harmful to a patient. 0 D. There is not enough information for any meaningful conclusionExplanation / Answer
1) the mean of the data is =(sum of all observation) / (total number of observation)
=138.5/10
=13.5
2)the mid range of data =((largest value)+(smallest value))/2
=(21+6)/2
=27/2
=13.5
3)To find median order the data from smallest to largest,
the data in accending order are,
6, 9, 12, 12, 13, 13.5, 14.5, 18.5, 19, 21
here the number of observations is even,
thus median is =(sum of middel two number)/2
=26.5/2
=13.25
4) the MODE of data is number which maximum time repeat ,
thus MODE= 12
5)The mode of data is =12 (option A with answer)
6) I choose the option D, because there is not enough information to make conclusion about
safety of medicine.such that the percentage of lead is harmful to patient.
7)They are not rounded.(option D). there is not need to be rounded the output.
there is seen a nothing but accuracy.
