Bicycles arrive at a bike shop in boxes. Before they can be sold, they must be unpacked, assembled, and tuned (lubricated, adjusted, etc.). Based on past experience, the shop manager creates a model of how long this may take based on the assumptions that the times for each setup phase are independent, each phase follows a Normal model, and the means and standard deviations of the times in minutes are as shown in the table. Complete parts a) and b).	Phase	Mean	SD
	Unpacking	3.3	0.8
	Assembly	23.9	2.7
	Tuning	12.7	2.8
