can anyone help solving these questions. urgently:

Question: draw random samples of size 2 using population units 2,4,6,8,10,12 . list all possible samples considering the population units only once and verify the following sampling distributions.

Question

(a) the weight of 9 boxes of cereal are 10.2 , 9.7 , 10.1 , 9.9 , 10.3 , 9.5 , 9.0 , 10.3 and 10.4 ounces . find the 99% confidence interval for the mean of all such boxes of cereal, assuming an approximate normal distribution. {t(8)(0.005)=3.355 OR z(0.005)=2.57 }
(b) Using the data of part A, test the hypothesis that the sample mean of these measurements significantly different with labeled weight 10.5 ounces, use 0.01 level of significance. {t(8)(0.005)=3.355 OR z(0.005)=2.57 }
