Question

find the mean of 6.5 ,8.2 , 9.4, 4.6 7.8 ,4.9​

Answer 1

✏Answer :

Mean= sum of all observations / number of all observations

$mean = \frac{6.5 + 8.2 + 9.4 + 4.6 + 7.8 + 4.9}{6} \\ mean = \frac{41.4}{6}$

✏ mean = 6.9

Answer 2

Mean = No. of observation ÷ Total observation

Mean = 6.5+8.2+9.4+4.6+7.8+4.9/6

mean = 37.31
