Step-by-step explanation:

$\tt\fcolorbox{red}{black}{\color{yellow}Solution} \: \ \\ \tt{mean \: = \frac{sum \: of \: observations}{total \: number \: of \: observations} } \\ \tt\therefore \bar{x} = \frac{ \sum \: xi}{n} \\ \tt= \frac{45 + 48 + 68 + 63}{4} \\ \tt= \frac{224}{4} \\ \tt= 56 \\ \tt\therefore \: \bar{x} \: that \: is \: average \: = 56$
