During one year, the numbers of motorcycle accidents in a certain country were tabulated by day of the week for built-up roads and non-built-up roads The data are shown in the table below. Complete parts (a) and (b) below. Click the icon to view the number of motorcycle accidents for different road types. a. Without doing any calculations, make an educated guess at which of the two data sets, built-up or non-built-up, has the greater variation. The non-built-up data set has greater variation, because the data set contains extreme observations. b. Find the range and sample standard deviation of each of the two data sets. Compare your results here to the educated guess that you made in part ( Find the range of the two data sets. The range of accidents on built-up roads is 33 . The range of accidents on non-built-up roads is 61. (Type whole numbers.) Find the sample standard deviation of the two data sets. The standard deviation for the number of accidents on built-up roads is The standard deviation for the number of accidents on non-built-up roads is (Type integers or decimals. Round to one decimal place as needed.)`Motorcycle Accidents By Road Type Day Built-up Non-built-up Monday 83 76 Tuesday 108 54 Wednesday 79 55 Thursday 98 50 Friday 110 43 Saturday 83 96 Sunday 77 104
