Question

The data set: 25, 45, 73, 16, 34, 98, 34, 45, 26, 2, 56, 97, 12, 445, 23, 63, 110, 12, 17, and 41.The mean of this data set is __________. (Please round to two decimal points.) A. 62.30 B. 63.15 C. 63.30 D. 63.70

Answer 1

D:63.70

Explanation:

We are given that a set of data

25,45,73,16,34,98,34,45,26,2,56,97,12,445,23,63,110,12,17,41.

We have to find the value of mean of given data .

We know that formula to find the mean =
`(sum\;of\;given\;data)/(total\;number\;of\;data)`

Total number of data =n=20

Substitute the values in the given formula then we get

Mean=
`(25+45+73+16+34+98+34+45+26+2+56+97+12+445+23+63+110+12+17+41)/(20)`

Mean=
`(1274)/(20)`

Mean=63.7

Hence, option D is true.

Answer: D:63.70
