Question 2
The following samples are observations taken from the same elements at two different times:
Unit Sample 1 Sample 2
1 15.1 4.8
2 12.3 5.7
3 14.9 6.2
4 17.5 9.4
5 18.1 2.3
6 18.4 4.7
Assume that the populations are normally distributed and construct a 90 confidence interval for the difference in the means of the distribution at the times in which the samples were taken.
A) (7.6232, 13.4434)
B) (5.2825, 15.8127)
C) (6.8212, 14.7821)
D) (7.4122, 14.6801)
