Find the critical values
χ2l=χ21−α/2 χ l 2 = χ 1 − α / 2 2 and χ2r=χ2α/2 χ r 2 = χ α / 2 2
that correspond to 80 % degree of confidence and the sample size
n=15.
χ2l= χ l 2 =
χ2r= χ r 2 =

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.
