Answer 1

Here, we have to use the given information to calculate the average (pooled) variance and the estimated error of the difference (between two means).

The detailed procedure to answer the given questions is as given in the images below:-

Here, we are given a table of Using the information, we have the following questions a information. to answer Q. 34) We have to compute the average B (pooled varianue). Answers Notice that, we have equal sample size. i.e. nic n2 = 8. Hence, for equal sample size, the formula for average (pooled) variance is *** 2 sp = 8 + 8 0 NA 2 Using the values from the table. 89 = 2.29 and 8 2 = 3.43. we get $P = 2.29 + 3. 43 - 5.12 = 2.86' & The average (pooted variance, 3 p = 2.86 २ 2

Que 35). Here, we have to compute the estimated error of the difference. We have the formula for the estimated error of the difference (between two means). iar - Using the values, Soz - 2.29 ; 82-3.43; 9,=12:8. Here, X, = M, 26 ; X2-M2=3. is 8C7; -72) = 8cnt, * Bew. - Wu) = 12:29 + 3,43 2.29 1-M2) = 5.72 5:42 8cm, - M2) = 10.715 = 0.8455 ✓ 0.84 Hence, the estimated error two means M, and M₂ of the difference (between A & (MILARS { 0.84

This answers your question.
