Question: The Employment and Training Administration reported that the U.S. mean unemployment insurance benefit was 5238 per week (The World Almanac. 2003). A researcher in the state of Virginia anticipated that sample data would show evidence that the mean weekly unemployment insurance benefit in Virginia was below the national average.
a. Develop appropriate hypotheses such that rejection of H0 will support the researchers contention.
b. For a sample of 100 individuals. the sample mean weekly unemployment insurance benefit was $231 with a sample standard deviation of $80. What is the p-value?
c. At α = .05. what is your conclusion?
d. Repeat the preceding hypothesis test using the critical value approach.
Show that the optimal modelfree lower bound for D is always less than or equal to f (So). Formulate and prove an analogous result for upper bounds.
A finite of length L that is fixed at both ends and is release from rest with an initial displacement will have the following mathematical description by the wave equation:
Define the degree of a continuous map f: Sn →Sn. Calculate, with some proof, the degree of the map f: Sn → Sn defined by f(v) = -v. Show that a map f: Sn → Sn of nonzero degree must be onto all of Sn
