Anu=75kg,Bindu=53 kg, Chandra =70 kg,Dinesh =64 kg,Enna = 72 kg,Fatima = 59 kg,Ganesh =71 kg, Hari = 58 kg ( a) If the lift can carry a weight of only up to 600 kg, are these people within the capacity of the lift? (b) Find the mean. (c) Is there any relevance of finding the median in this data? ( D) Is there any relevance of finding the mode of this data?​

Answer 1

Answer:

a) All can travel safely as their overall weight (532kg) is below 600 kg and is appropriate.

b)mean= 532/8

=66.5 kg

c) No, there is no relevance of finding the median as the data is even in number.

d) No, there is no relevance of finding the mode as no number is repeated.

Answer 2

Step-by-step explanation:

a) Total weight = 522kg, yes these people are within the capacity of the lift.

b) Mean = 522/8

= 65.25kg

c) Given data,

53kg, 58kg, 59kg, 64kg, 70kg, 71kg, 72kg, 75kg

Median = (64+70)/2

= 67kg

d) there's no number which has frequently occurred. hence it's irrelevant to calculate the mode.
