Explanation / Answer

(a) Mean = 3068/7 = 438.2857

(b) Arrangind data in ascending order, we get:

308,369,376,382,519,549,565

n = 7

Median is 1/2 (n+1)th item = 4th item = 382

Median = 382

(c) Midrange:= (maximum + minimum)/2 = (565 + 308)/2 = 436.5

(d) Mode = NIL, REASON: All values appear just once
