Answer: (13.4996, 32.5004)
Step-by-step explanation:
The confidence interval for mean difference is given by :-
,
where 
= sample mean difference .
= critical t value (two-tailed)
SE= Standard error.
Given : 
SE= 4.2
Now, the confidence interval for mean difference will be :-
Hence, the required confidence interval : (13.4996, 32.5004)
Answer:
x=1 & y=6 or (1,6)
Step-by-step explanation:
3x-x+5=7 Substitute the 2nd equation in for y
2x+5=7 Do 3x-x to get 2x
2x=2 Subtract 5 from both sides
x=1 Divide 2 from both sides
y=1+5 Insert 1 as x
y=6 Add 1+5 to solve for y
