Answer:
a) 97.37%
b) 1.31%
Step-by-step explanation:
a)
Here we want to calculate the area under the Normal curve with mean 0.52 and standard deviation 0.009 between 0.5 and 0.54
This can be easily done with a spreadsheet and we get
<em>P (0.5くV < 0.54) = 0.9737 or 97.37% </em>
(See picture 1)
b)
Here we want the area under the Normal curve with mean 0.52 and standard deviation 0.009 to the left of 0.5.
<em>P(V ≤ 0.5) = 0.0131 or 1.31% </em>
(See picture 2)
