As a vaccine scientist, you are required to test your newly developed vaccine in two different populations, populations Xand Y to ensure the safety and effectiveness of the vaccine. There are 3190 subjects from database X and 6094 subjects from database Therefore, you must select a number of subjects from populations X and Y to form a group. The newly formed of group must consist of subjects from both populations without repetition. The maximum number of groups which can be formed is denoted as d.
(1) Use Euclidean algorithm to find d=GCD(X,Y).
2) Find the integers s and tsuch that d=sX+tY
3) With the answer obtained from a, what is the ratio of subjects selected from population X and Y,PX:PY.
4) Find Least Common Multiple for X and Y,LCM(X,Y).

Given:
X=3190 and
Y=6094
(1) Set up a division problem where a is larger than b.a÷b=c with remainder R. Then replace a with b, replace b with R and repeat the division. Continue the process until R=0
6094=1×3190+2904
3190=1×2904+286
2904=10×286+44
286=6×44+22
44=2×22+0
When remainder R=0, the GCD is the divisor, b, in the last equation. GCD=22
GCD(3190,6094)=22
(2) Finding linear combination of 3190 and 6094
22=3190(128)+6094(67)
so s=128 and t=67
(3)PxPy=31906094÷2222=145277
(4) LCM of 3190 and 6094
3190=2×5×11×29
6094=2×11×277
Multiply each factor the greatest number of times it occurs in either 3190 or 6094
=2×5×11×29×277
=883630
Thus, LCM is 883630

Effect of alcoholic parents A study1 compared personality characteristics between 49 children of alcoholics and a control group of 49 children of nonalcoholics who were matched on age and gender. On a measure of well being, the 49 children of alcoholics had a mean of 26.1(s=7.2) and the 49 subjects in the control group had a mean of [28.8(s=6.4)]. The difference scores between the matched subjects from the two groups had a mean of 2.7(s=9.7).

The other group of 12 participated in the survey after studying for three twenty-minute sessions.
As per the survey, results group 1 had a mean score of 75 and a variance of 120.
Second group had a mean score of 86 and a variance of 100. Assuming the normal populations, independent samples, and equal population variances conditions hold, are the mean test scores of these two groups significantly different at the 0.05 level?
