In the Norwegian box office hit film Il Tempo Gigante, it was said that on Reodor Felgen's first run of his racing car Il Tempo Gigante, the seismograph in Bergen registered it as an earthquake in Flåklypa of magnitude 7.8 on the Richter scale. For extra observations, the seismograph in Reykjavik registered it as 7.6, and the one in Helsinki had it at 7.9. Use a neutral prior, and find a 95\% credible interval for the magnitude of the earthquake in Flåklypa when Felgen drove off in his Il Tempo Gigante.
