Assume that the Richter scale magnitudes of earthquakes are normally distributed with a mean of 1.157 and astandard deviation of 0.532. Complete parts a through c below. Will all earthquakes above the 95th percentile cause indoor items to shake?O A. Yes, because earthquakes above the 95th percentile are very rare and powerful.B. Yes, because all earthquakes above the 95th percentile have magnitudes above 4.0.C. No, because no earthquakes above the 95th percentile have magnitudes above 4.0.D. No, because not all earthquakes above the 95th percentile have magnitudes above 4.0.

The mean is 1.157 and the standard deviation is 0.532.
