- Scatter plotsUse the estimate yest=3.3x2 - 9.4x - 0.1 to calculate a set of residuals, using a formula or a calculator. Explain your steps, then create a residual plot using this new model and assess its validityAt Center Hospital there is some concern about the high turnover of nurses. A survey wasdone to determine how long (in months) nurses had been in their current positions. Theresponses (in months) of 20 nurses were 23251425362742128723292628112031836 A box-and-whisker plot of the data is shown below.
- When creating the dot plot, how are multiple data points for a single score displayed? a. A larger size dot is used; the size of the dot is directly proportional to the number of data points. b. More than one dot is used; dots are placed side by side creating a wider interval. c. A dot plot is innappropriate when multiple data points exist for a single score. d. Multiple dots, representing each data point, are replaced on top of one another.Use a box-and-whisker plot to describe how the data are spread about the median.
