Answer #1

Given that :

constant rate \lambda = 0.05

Average = Mean = Expected value = \mu = 1/\lambda = 1/ 0.05

Average number of days between 6th and 7th earthquakes is 1/0.05 = 20 days

    A6. Earthquakes in Christchurch, New Zealand occur as a Poisson process over time at a constant rate 0 per day. (a) Show that the number of quakes over a d-day period follows a Poisson distri- bution with parameter Od. (b) Given that 12 quakes have happened over a 10 day period, derive the distri- bution for the number of quakes that occurred during the first 4 days of the period. Note: If X has a Poisson distribution with parameter 0,...

    According to a 2011 report by the United States Department of Labor, civilian Americans spend 2.75 hours per day watching television. A faculty researcher, Dr. Sameer, at California Polytechnic State University (Cal Poly) conducts a study to see whether a different average applies to Cal Poly students. Suppose that for a random sample of 100 Cal Poly students, the mean and standard deviation of hours per day spent watching TV turns out to be 3.01 and 1.97 hours, respectively. The...
