If we have a large voluntary response sample consisting of weights of subjectswho chose to respond to a survey posted on the Internet, can a graph help toovercome the deficiency of having a voluntary response sample?Choose the correct answer below.O A. No, a graph cannot help to overcome the deficiency. If the sample is a badsample, there are no graphs or other techniques that can be used tosalvage the data.O B. Yes, a graph can help to overcome the deficiency. Certain graphs thathide any specific values in the data, such as pie charts, can be used tohide deficiencies in the sampling technique.O C. No, a graph cannot help to overcome the deficiency Before graphing, allinaccurate values and outliers must be removed from the data set.O D. Yes, a graph can help to overcome the deficiency. Any graph that is givenwith a sufficiently accurate description of any deficiencies in the samplingtechnique is no longer considered biased.Next Construct a stem-and-leaf plot of the test scores67, 72, 86, 75, 89, 89, 88, 90, 98, 100.
