Sagot :
Solution:
Add all the numbers in the data set together. then divide by the total number of values in the data set.
[tex] \: \: \: \: \: \: \sf \: μ = \frac{8 + 2 + 9 + 7 + 1 + 9}{6} \\ \\ \: \: \: \: \: \: \sf μ = \frac{36}{6} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \sf μ = 6 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: [/tex]
Add all the number given , after you get the total divide it into given number
Mean= 8+2+9+7+1+9=36
Mean= 36/6 = 6
Mean= 8+2+9+7+1+9=36
Mean= 36/6 = 6
