Answer 1

Page No.: Date: 1 Sample size (n)=5. sample values : 6,6 5 , 6, 7-5,5 Formula is as for the standard error of the sample mean follows SE= Standard deviation of the sample SE = S where, sal (;- 7j2 and t= {xi B -1 > 1 .: . 6+6.5 +6+7-5 +5 31 = 6.2

.: S = 0.9082951062 .: Standard error = s = 0.9082951062 Tă J5 .: standard error = 0.40620192 That is standard error of the sample mean is, 0.41 So, option © is correct
