Note: If the alpha level is not included, set the alpha to .05. Problem 1: The Graded Naming Test (GNT) asks respondents to name objects in a set of 30 black and white drawings in order to detect brain damage. The GNT population norm for adults in England is 20.4. Researchers wondered whether a sample for Canadian adults had different scores from adults in England (Roberts, 2003). If the scores were different, the English norms would not be valid for use in Canada. The mean for 30 Canadian adults was 17.5. Assume that the standard deviation of the adults in England is 3.2. How can we calculate a 95% Confidence Interval (CI) for these data?

Calculate a 95% CI and a 90% CI for this data.

Are the English norms valid for use in Canadian use?

Explain how you know your answer to be true.

How do the two CI’s (95% and 90%) compare to one another?

What is the effect size for these data?

What does this effect size indicate about the meaningfulness of this test for Canadians?

What would you recommend doing to increase the power of this experiment?

7. Show that the dual space H' of a Hilbert space H is a Hilbert space with inner product (', ')1 defined by
(f .. fV)1 = (z, v)= (v, z), where f.(x) = (x, z), etc.

A Si pn diode has an equilibrium diffusion barrier of 0.7 V and an area capacitance of C2D = 4 nF/cm2 for a reverse bias voltage of -4.3 V. What can you tell about the doping levels?

verify the maxwell relations associated with the helmholtz free energy F and the Gibbs free energy F by using the equaiton of state an ideal gas and the expressions for S(T,V) and S(P,V) when c_v is constant.

Give an algorithm that constructs an undirected connected graph, which allows for labeling of the n vertices u - v <= k for every edge (u,v), where k is some constant. All nodes have a unique label.

A mass (m) with speed (v) experiences a perfectly elastic collision with an initially stationary mass (M). What is the ratio of the masses (m/M) if after the collision, m and M have the same speed (V) but opposite velocities?

1. In the L/N column in the table below, please type V if the value is a valid python integer value or N if the value is not a valid python string value.

1) a) Derive a relationship between the electric field (E) and electric potential (V) knowing that V is defined as the energy per unit test charge.

b) Based on the above derivation, state an alternate acceptable unit for (E).

Find out the consumer price index(CPI) and the inflation rate for the information given below:
Base year is 2016
Basket of goods in 2016 costs 3550 DHS
Basket of goods IN 2017 costs 3850 DHS
Basket of goods IN 2018 costs 4550 DHS

Find out:
CPI for 2016
CPI FOR 2017
CPI for 2018

Using these information above find out the following
(i) price increase inflation rate between 2016 and 2017
(ii) price increase inflation rate between 2017 and 2018
