Since 1900, the magnitude of earthquakes that measure 0.1 or higher on the Richter Scale in CA are distributed normally with a mean of 6.2 and a standard deviation of 0.5, according to the USGs.
a.) What is the probability that a randomly selected earthquake in CA has a magnitude greater than 7.1?
b.) What is the probability that a randomly selected earthquake in CA has a magnitude less than 5.1?
c.) What is the probability that ten randomly selected earthquakes in CA have mean magnitude greater than 6.1?
d.) What is the probability that a ten randomly selected earthquakes in CA have mean magnitude between 5.7 and 7.22
e.) Determine the 40th percentile of the magnitude of earthquakes in CA.
