Answer:
option C
Step-by-step explanation:
given,
α = 1 - 0.95 = 0.05
degree of freedom (df) = 17 -1 = 16
critical value (from t-table)
margin of error =
=2.120\times \sqrt{\dfrac{25.36^2}{17}+\dfrac{25.183^2}{17}}[/tex]
= 2.120 x 8.6467
= 18.33
Margin of error = 18.33
Point estimation of difference =
= 36.235
lower limit = 36.235 - 18.33 = 17.91
upper limit = 36.235 + 18.33 = 54.57
hence, the nearest option near to answer is option C
Answer:
I believe it is not. that would mean 7=-3+15 and therefore 7=12, which is not a true statement.
Answer:
/
Step-by-step explanation:
firstly we make two steps to simplify this question.
1st step: simplify
to simplify this we use factorization
.....(1)
2nd step:simplify
.....(2)
now dividing (1) and (2), we get the answer
Am not good at that much but let me try
