Our natural resources are valuable and important to sustain so that we have continued access to these resources in the future. Please answer the following: What is a company’s obligation to contribute to the natural resource’s sustainability? If so, what does that obligation look like? Is this limited to local resources or globally as well

Discuss other systems and their artifacts we might find. This class revolves around a traditional computer. What other devices could we forensically image that may contribute data or forensic information that may be located in our homes? Are there privacy concerns? Anyone hear of an Amazon Echo?

2. List a variety of ways to remind your staff and colleagues of your ethical standards. How do you, as an employee, convey the management's ethical standards?

Find the lower fence for the following data set: 45, 34, 27, 78, 42, 64, 78

Find the upper fence for the following data set: 3, 19, 47, 18, 23, 34, 45, 27, 10, 7

Three equal impedances, (8+j6) ohms are connected in wye across a three-phase, three-wire supply. The symmetrical components of the phase A line voltages are:

Va0 = 0

Va1 = 220 + j 28.9 V

Va2 = -40 - j 28.9

If there is no connection between the load neutral and the supply neutral, Calculate the symmetrical currents of line a,b, and c.

An analyst at a local bank wonders if the age distribution of customers coming for service at his branch in town is the same as at the branch located near the mall. He selects 100 transactions at random from each branch and researches the age information for the associated customer. Use the table below to answer the questions.

1. What are the null and alternative hypotheses?

a. Ho: The age distributions of customers at the two branches are not the same.

     Ha: The age distributions of customers at the two branches are the same.

b. Ho: Age is not independent of branch.

    Ha: Age is independent of branch.

c. Ho: The age distributions of customers at the two branches are the same.

    Ha: The age distributions of customers at the two branches are not the same.

d. Ho: Age is independent of branch.

    Ha: Age is not independent of branch.

2. What type of test is this?

a. Chi-square goodness-of-fit-test

b. Chi-square test of independence

c. Chi-square test of homogeneity

3. What are the expected numbers for each cell if the null hypothesis is true?

4. Find the X2 statistic.

X2 =               (round to two decimal places)

5. How many degrees of freedom does the X2 statistic have?

df =

6. Find the critical value at alpha = 0.05

X2 =               (round to three decimal places)

7. What do you conclude?

The test statistic is (greater than or less than) the critical value. There is (insufficient or sufficient) evidence to reject Ho.
