1/7p = 3
Multiple both sides by 7
7 x 1/7p = 7 x 3
Then cross multiply
P= 21
Multiple both sides by 7
7 x 1/7p = 7 x 3
Then cross multiply

Answer: 2.14 %
Step-by-step explanation:
Given : pH measurements of a chemical solutions have
Mean :
Standard deviation :
Let X be the pH reading of a randomly selected customer chemical solution.
We assume pH measurements of this solution have a nearly symmetric/bell-curve distribution (i.e. normal distribution).
The z-score for the normal distribution is given by :-
For x = 6.74
For x = 6.76
The p-value =
In percent,
Hence, the percent of pH measurements reading below 6.74 OR above 6.76 = 2.14%
