(Solved) : Ph Pure Water 25 Degrees C 7 Measured Using Given Meter Measured Ph Actually Varies Measur Q32562470 . . . .

 

The pH of pure water at 25 degrees C is 7. When measured using a given meter, the measured pH actually varies from measurement to measurement with an approximate normal distribution, with a mean measured pH of 7.0 and a standard deviation of 0.07. The measurements have an approximate normal distribution. What is the probability that the measured pH is less than 7.2? a 0.50 b.0.1 C.2.86. d.0.0021. e 0.998
