Answer 1

Solution : Given data for chocolate bar per minute is - time chocolate bars 9:47 am 53 11:12 am 1:00 pm 2:35 pm 3:56 pm yo 5:13 pm 6:04 pm - 57 ری 47 (a) mean = chocolate sum of all bars produced number of times measurement of counting obserbed 53 +50 + 47+55 t yo+47 +57 - 49.857 = 50 (6) Median : all order first we need to arrange data in increasing 40 47 47 50 53 55 57

Median is knotun as central value proud Haceasing ordered data If no. of data points (2) is odd, - median - intl)th value from - moreasing ordered data If no, of dater points (o) is even median – everage of ( th and (2 + 1)th value from increasing ordered data. & In our case, no. of data points = 7 median - (+1)th value = 4th value = 50 (c) Modal no. of chocolate bars = - data repeated maximum no. of times 4 (repeating two times) =
