Question:
Refer to the data on earthquakes of magnitude greater than 6.5 in Exercise 2.20. The data suggests that one plausible model, for X = magnitude, is a population distribution having mean μ = 7 .05 and standard deviation σ = .43. Calculate the expected value and standard deviation of X̅ for a random sample of size (a) 9 and (b) 16.
Data from in Exercise 2.20
In a recent year, 35 sites around the world experienced earthquakes of magnitude greater than 6.5.
Construct a histogram using equal-length intervals starting with (6.5, 6.8 ], where the right-hand endpoint is included but not the left-hand endpoint.
