ABLE 3: QUARTER TWO CRIME STATISTICS IN THE WESTERY CAh FROM 2020 TO 2022. e TABLE 3 above to answer the questions that follow Determine the value of Quartile 2, for the number of crimes commited 2020. 2 If the number of eases for theft from vehicles increased by \( 20,8 \% \) in 2022 Calculate to the nearest hundred, the number of eases from motor vehicle in 2021. 3 Calculate the percentage change in the number of Carjacking between 20 and 2022. You may use the following formula: \[ \text { \%Increase }=\frac{\text { Number of Carjacking in 2022-Number of Carjacking in } 2021}{\text { Number of Carjacking in } 2021} \times 10 \] State, giving a reason, whether the data given in the \% change colum discrete or continuous data.
