Answer:
Test = 17.143 ;
Pvalue = 0 ;
Reject the Null ;
(-0.028 ; - 0.022) ;
We conclude that content are different.
Step-by-step explanation:
Given that:
μ1 = μ
n1 = 36 ; n2 = 36
x1 = 0.78616 ; x2 = 0.81111
s1 = 0.04444 ; s2 = 0.00752
Test statistic :
(x1 - x2) / √(s1²/n1 + s2²/n2)
(0.78616 - 0.81111) / √(0.00444²/36 + 0.00752²/36)
- 0.02495 / 0.0014554
= 17.143
Pvalue :
Z < 17.143
Pvalue = 0
Since Pvalue < α ; Reject the Null
The confidence interval using a confidence interval calculator is (-0.028 ; - 0.022)
Since the interval does not contain Zero ; then we reject the Null and conclude that the content are different.
Solving 6 sets of equations borders on "too complex". It is nice to have a graphing calculator that does this easily.
