Answer:
we can conclude that there is significant evidence to support the stance that mean pH value in water differs from 8.5
Step-by-step explanation:
H0 : μ = 8.5
H1 : μ < 8.5
Test statistic :
(xbar - μ) / s/sqrt(n)
(8.24 - 8.5) ÷ (0.16 ÷ √12)
-0.26 ÷ 0.0461880
Test statistic = - 5.63
The Pvalue can be obtained from the test statistic value using a Pvalue calculator :
df = 12 - 1 = 11
Pvalue = 0.000077
Using an α value of 0.05 ; we can conclude that
Pvalue < α ; We reject H0
Hence, we can conclude that there is significant evidence to support the stance that mean pH value in water differs from 8.5
An example should help you understand
(3 + 2) + (8 +1)
= 9* + 1) + (3 + 2)
= 3 + (2 + 8 + 1)
= 2 + 3 + (1 + 8)
all of these have the same sum.
Answer:
I believe its -7/5 unless they want -7/-5
Step-by-step explanation:
(4,3) (-1,-4)
X1,y1 x2,y2
And it should be
Y2-y1
X2-x1
-4-3 = -7
Over
-1-4 = -5
So -7/5 or -7/-5 whatever your teacher perfers
