(a) Explain the concept of a post-data severity assessment and use it – in the context of a simple Bernoulli model– to evaluate the severity of the N-P decision for the hypotheses: H0: θ ≤ .5, vs. H1: θ > .5, using the data in Table 13.2, by evaluating the different discrepancies γ = .01, .014, .0145, .015, associated with θ1 = θ0+γ

using the data in table 2.

(b) Compare and contrast the severity curve in

(a) with the power curve for the same discrepancies γ = .01, .014, .0145, .015.

(c) What is the discrepancy γ from θ0 = .5 warranted by the data in Table 13.1 for a severity threshold of .95?
