A corporate trainer administered a test to eight employees prior to their participation in a training program. The trainer administered the test again after participation. Raw test scores from each administration are as follows:

Test-Taker First Administration Second Administration

John 6 6

Doug 5 4

Christina 8 7

Sammy 4 2

Todd 4 8

Terri 2 1

Abel 6 7

Theresa 3 3

Answer the following questions

1. What is the test-retest reliability coefficient for the test?

2. What is the standard error of measurement for the first and second administration?

3. What is the confidence interval at which we may be 95% certain of Abel's true score on the first administration? Given the confidence interval, could we feel confident that Abel's true score on the first administration is higher than Todd's true score on the first administration?

The table below reports the market demand schedule of Coca Cola and Pepsi.

1. Calculate the elasticity of demand for Coca Cola when its price increases from MYR 4 to MYR 5. Is the demand elastic, inelastic or unit elastic at this price range? Briefly explain.

2. If the demand for Coca Cola is inelastic, what would happen to the total revenue if price increases? Briefly explain.

3. Find the cross price elasticity between Coca Cola and Pepsi when the price of Coca Cola increases from MYR 2 to MYR 3.

4. What can you say about these two goods? Are they substitute or complement? Briefly explain.

6. A medical researcher wishes to try three different techniques to lower blood pressure of patients with high blood pressure. The subjects are randomly selected and assigned to one of three groups. Group 1 is given medication, Group 2 is given an exercise program, and Group 3 is assigned a diet program. At the end of six weeks, each subject’s blood pressure is recorded. Alpha=.05

(a) What will an ANOVA test do in this situation?

(b) State the hypotheses for this ANOVA test.

(b) Create an ANOVA summary table for the test statistic F. You can use Stat-Test-ANOVA (or other technology) to create the chart.

(c) Using either the rejection region or the p-value, decide if you should reject the null hypothesis.

(Compute FIFO, LIFO, Average-Cost—Periodic and Perpetual) – Use your notes to follow the process through

(LO 3) Ehlo Company is a multiproduct firm. Presented below is information concerning one of its products, the Hawkeye.

Instructions

Compute cost of goods sold, assuming Ehlo uses:

(a) Periodic system, FIFO cost flow.

(b) Perpetual system, FIFO cost flow.

(c) Periodic system, LIFO cost flow.

(d) Perpetual system, LIFO cost flow.

(e) Periodic system, weighted-average cost flow.

(f)  Perpetual system, moving-average cost flow.

Part B: Which is higher, the initial state energy or the final state energy of the atom if n=1, n′=3?

Part C: For the hydrogen transition indicated below, with n being the initial state and n′ being the final state, is the transition an absorption or an emission?
n=6, n′=2.

Part D: Which is higher, the initial state energy or the final state energy of the atom if n=6, n′=2?

Part E: For the hydrogen transition indicated below, with n being the initial state and n′ being the final state, is the transition an absorption or an emission?
n=4, n′=5

Part F: Which is higher, the initial state energy or the final state energy of the atom if n=4, n′=5?

Part G: Finally, which of these transitions involves the largest energy photon?

- n=4, n′=5

- n=6, n′=2

- n=1, n′=3

Exercise.

Practice redirection to change the above commands so that:

(i) error messages are sent to /dev/null, but

(ii) we still detect errors and halt execution of the sequence appropriately.

For i, recall from prior labs that standard error stream (stderr) is #2, and you will need redirection to route an error normally to stderr to /dev/null.

Hint: Recall that redirection happens per process executed. So, what do you need to add to each process to make the redirection successful?

Below are 4 commands to rewrite:

#1) ls . && ls -! && ls -al || echo "We Failed"

#2) ls -! && ls . && ls -al || echo “We Failed”

#3) ls . && ls -al && ls -! || echo "We Failed"

#4) ls . && ls -al || echo “We Failed”

Write a new version of each by copying the list below, and add your revisions to the four above commands:

To understand the value of counting loops:

1. Write a java program that implements matrix multiplication using counting loop constructs.
2. Then write the same program using only logical loops—for example, while loops.
