You are advised to plot the graphs of the data given in Tables 1 and 2 below (on a separate spreadsheet) in order to answer the questions.

TABLE 1

The data below shows the number of cars per minute entering a car park.

Number of cars	0	1	2	3	4	5	6	7	8
Frequency	4	17	26	32	19	10	4	2	1

TABLE 2

The data below shows the time taken, to the nearest minute, for employees at a clothing manufacturer to produce a shirt.

Time (min)	20	21	22	23	24	25	26	27	28	29	30	31	32	33	34
Frequency	3	10	18	29	43	53	56	52	41	26	18	13	8	5	2

1)	Decide whether you think the following statements are TRUE or FALSE.

First	The data in TABLE 1 follow a Normal Distribution.
Second	The data in TABLE 2 follow a Normal Distribution.

If you think:	First	Second		then Enter
	TRUE	TRUE		1
	TRUE	FALSE		2
	FALSE	TRUE		3
	FALSE	FALSE		4
					(1, 2, 3 or 4)

2)	Use your graph for the data in TABLE 2 to determine, to the nearest minute,

the mean time for an employee to produce a shirt.
