Question

find the mean big data 10. 25,9,4.75,8,2.65,12,2.35​

Answer 1

Step-by-step explanation:

MEAN= SUM OF OBSERVATIONS

_____________________

TOTAL NUMBER OF OBSERVATIONS

10.25+9+4.75+8+2.65+12+2.35/7

= 49/7

=7

Answer 2

Answer:

Given, observations 10.25, 9, 4.75, 8, 2.65, 12, 2.35

Given, observations 10.25, 9, 4.75, 8, 2.65, 12, 2.35Clearly, No of observations, n = 7

Given, observations 10.25, 9, 4.75, 8, 2.65, 12, 2.35Clearly, No of observations, n = 7We know,

$x = \frac{10.25 + 9 + 4.75 + 8 + 2.65 + 12 + 2.35 }{7}$

$x = \frac{49}{7} = 7$
