Answer: ($3.055, $3.205)
Step-by-step explanation:
Given : Significance level : 
Critical value : 
Sample size : n= 36
Sample mean : 
Standard deviation : 
The confidence interval for population mean is given by :_


Hence, the 95% confidence interval to estimate the population mean = ($3.055, $3.205)
Maybe because you're finding the "difference" between the two numbers. We could also question why the answer to an addition problem is called sum.
Well, 'sum'body said that's what they should be called a long time ago, that's why we're using that term to call them now.
A) (1, 7) Doesn't
B) (0, 4) Doesn't
C) (2, –2) Doesn't
D) (3, –5) DOES
All the steps are right at the exception of line 7 (and onwards)
line 6 : 6x = 42 (it's right). Now divide both sides by 6:
line 7 should be: 6x/6 = 42/6
line 8 should be: x = 7.
