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? 19 5.5 3.5 21 19.5 10.5 Find the mean, midrange, median, and mode of the data set The mean of the data set ismg/g (Type an integer or a decimal. Do not round.) The midrange of the data set ismg/g (Type an integer or a decimal. Do not round.) The median of the data set ismg/g (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 ( A. The models) of the data set is (are) Type an integer or a decimal. Do not round. Use a comma to separate answers as needed.) B. There is no mode What do the results suggest about the safety of this medicine? Choose the correct answer below. A. The lead content in this medicine is lethal to a patient B. The lead content in this medicine is harmful to a patient C. The lead content in this medicine is not harmful to a patient ( D. There is not enough information for any meaningful conclusion What do the decimal values of the listed amounts suggest about the precision of the measurements? Choose the correct answer below A. They are rounded to one half unit measurements O B. They are rounded to one tenth unit measurements ° C. They are rounded to one quarter unit measurements 0 D. They are not roundedExplanation / Answer
Mean = (19 +9 +19 + 11+5.5 + 3.5+ 21+7+ 19.5 +10.5)/10 = 12.5
Midrange = (2.5 + 21)/2 = 11.75
Data in ascending order - 3.5,5.5, 7, 9, 10.5, 11, 19, 19, 19.5, 21
Median =(10.5+11)/2 = 10.75
Mode - 19
Regarding safety
D. There is not enough information for any meaningful conclusion
Regarding precision,
A. They are rounded to one half unit measurements
