Consider the plot below. Use this plot to answer the following questions. Data set I Data set 20 30 35 45 50 60d) Which of the following cant be justified? The range of data set I equals the range of data set Il The IQR of data set I equals the IQR of data set ll The median of data set is less than the median of data set ll -〉 . o Data set I and data set II have the same number of data points. About 75% of the of the values in data set 11 are greater than or equal to about 50% of the values in data set l.Dutch Elm disease is one of the most destructive Urban Forest Diseases which affects native Elm species. Since its introduction into the US in the 1930s it has caused the distruction of most of the American Elm populations in the Northeastern and Midwestern states. A forestry graduate student is studying Dutch Elm disease in Texas. there are 1500 Elm trees in the graduate students study. (Assume the trees were randomly chosen from around the state.) Of these trees, 17 (1.1%) had Dutch Elm disease. (a) What are the subjects in this sample? All trees in Texas O All Elm trees in Texas All diseased Elm trees in Texas The 17 diseased Elm trees The 1500 Elm trees in the study (b) What is the population? choose the best answer All trees in Texas All Elm trees in Texas All diseased Elm trees in Texas The 17 diseased Elm trees O The 1500 Elm trees in the study(d) What is the statistic of interest? The number 1.1% OThe number 1500 OAll diseased Elm trees in Texas Whether or not a tree is an Elm tree O Whether or not an Elm tree had Dutch Elm diseasee Both 1.1% and 1500 are statistics
