Since, the correlation between set 1 with set 2 and set 3 is 1.Which tells that there is perfect linear correlation between set 1 with set 2 and set 3.That is, as the value of set 1 increases the value of set 2 and set 3 also increases.
A)
The mean of the first set is 14.5 and of second set is 7.5.The standard deviation of first and second set is same i.e. 1.2910.
Which tell that variation is same in both cases.The value of both set increases of decreases simultaneously.
B)
The mean of the first set is 7.5 and of second set is 15.The standard deviation of second set is 1.291 and third set is 2.582.
The variation in set 3 is twice the variation set 2.The value of both set increases of decreases simultaneously with factor of 2.

Two independent samples were selected from a population with mean µ=210 and standard deviation s=100. The first sample, Group 1, included 49 patients, and the second sample, Group 2, had 64 patients. Now, we like to estimate the standard deviations of the means in Group 1 and Group 2. Which of the following answers are right? a Both standard deviations of the means in Group 1 and Group 2 are 100. b The standard deviations of the means in Group...
