The effect of a monetary incentive on performance on a cognitive task was investigated. The researcher predicted that greater monetary incentives would result in higher performance. Participants were told that they would receive either 5 cents, 25 cents, or 50 cents for each word puzzle that they correctly solved. A statistical test showed that there was a significant effect of incentive on performance at the .01 level. The greater the incentive, the more puzzles were solved. 1.) What statistical test was performed? 2.) Explain why rejecting the null hypothesis does not mean that the results of a study prove that the null hypothesis is false.

The introduction should describe the impact of the problem on your community and rationale for its selection.

Identifies, describes, and justifies your selection of the level of the public health pyramid at which the assessment will be conducted Develops a needs assessment plan for addressing the selected problem in your community.

Let’s say that at t=0 the hydrogen atom is in the state that is described by the following wave function:

Ψ(r,0) = N{ψ211(r,θ,φ) + 1/4ψ32-1(r,θ,φ)+1/4ψ320(r,θ,φ)}

where ψ are the the normalized eigenfunctions of the hydrogen atom.

For a random time t calculate

1. The normalized wave function Ψ(r,t)

2. The expected value of the z component of the angular momentum, <Lz>

3. The expected value of the square of the angular momentum, <L^2
