Consider the following dataset, which captures relapse/no-relapse of 20 individuals after treatment within a correctional facility. The data are coded in a way that 0 indicates no relapse and 1 indicates relapse.
a. Indicate how many individuals fall in category 0 and how many in category 1 (counts).
b. Compute the percentages of individuals who did not relapse after treatment in a corrections facility and that of individuals who did relapse.

$\begin{array} { l l } \text {ID }&\text {Relapse/}\\\text {No.}&\text { no relapse}\\1 & 0 \\ 2 & 0 \\ 3 & 1 \\ 4 & 1 \\ 5 & 1 \\ 6 & 0 \\ 7 & 1 \\ 8 & 1 \\ 9 & 0 \\ 10 & 0 \\ 11 & 0 \\ 12 & 1 \\ 13 & 1 \\ 14 & 1 \\ 15 & 1 \\ 16 & 1 \\ 17 & 0 \\ 18 & 1 \\ 19 & 1 \\ 20 & 0 \end{array}$
