Answer #1

the needed calculation table be:-

data (x) x2
12 144
40 1600
31 961
23 529
13 169
17 289
sum=136 sum=3692

number of observations (n) = 6

here, as nothing is mentioned i am calculating both sample and population sd.

the sample standard deviation be:-

the population standard deviation be:-

*** if you have any doubts about the problem please mention it in the comment box... if satisfied please LIKE.
