The following data on number of minutes used for cell phone calls in 1 month was generated to be consistent with summary statistics published in a report of a marketing study of a city's residents. 1890 189 177 106 205 0 212 0 309 0 59 224 0 189 142 83 71 165 0 238 0 142 238 120 USE SALT (a) Calculate the values of the quartiles and the interquartile range for this data set. lower quartile = upper quartile = interquartile range (b) Explain why the lower quartile is equal to the minimum value for this data set. Will this be the case for every data set? Explain. The lower quartile is equal to the minimum value for this data set because there are a ---Select--- number of equal values at the ---Select--- end of the distribution. In most data sets this ---Select-- the case and therefore, generally speaking, the lower quartile ---Select--- equal to the minimum value.

interquartile range =
(b) Explain why the lower quartile is equal to the minimum value for this data set. Will this be the case for every data set? Explain.
The lower quartile is equal to the minimum value for this data set because there are a ---Select--- number of equal values at the ---Select--- end of the distribution. In most data sets this ---Select--- the case and
therefore, generally speaking, the lower quartile [---Select--- equal to the minimum value.
Transcribed Image Text:A woman sued a computer keyboard manufacturer, charging that her repetitive stress injuries were caused by the keyboard.
The jury awarded about $3.5 million for pain and suffering, but the court then set aside that award as being unreasonable
compensation. In making this determination, the court identified a "normative" group of 27 similar cases and specified a
reasonable award as one within 2 standard deviations of the mean of the awards in the 27 cases. The 27 award amounts (in
thousands of dollars) are in the table below.
