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

Answer:
14 liters
Step-by-step explanation:
10 liters : 4 liters of juice and 6 liters of water
4/10 of juice and 6/10 of water
make it to 70% of juice and 30% of water
add 14 liters of juice
14/20=70% of juice
6/20=30% of water
