Step 1: Solve the following problems.
Use a program (such as MS Word) to write your solutions to the following problems. Use the appropriate t-test to test for significant mean differences in the following research scenarios. Report all relevant information, including hypotheses, degrees of freedom, critical value, and a statement about significance. 1.Dr. Smith conducted an experiment to study the effects of massed versus distributed practice on memory. Twelve participants were randomly assigned to study a short chapter of a history text during either a single 3-hour session or 3 one-hour sessions separated by 24 hours. Twenty-four hours after the study session(s) ended, the participants took an examination on the information in the chapter and the number of correct answers was recorded. Data from that experiment are shown below. Massed PracticeDistributed Practice

X1 = 58.83 | X2 = 74.67 |
S1 = 8.50 | S2 = 7.23 |
Step 1: H0: x̄1=x̄2 H1: x̄1≠x̄2
Step 2: df= 6+6-2= 10
Step 3: find critical value for t at the .05 level of significance. t crit = 2.228 Step 4: calculate t =4.6
Step 5: compare t to tcrit: Is 4.6 ≥ 2.228? YES! Therefore, we reject the null hypothesis.

2.A researcher wants to see if antihistamines will increase the amount of time in seconds it takes participants to react to a surprise stimulus. He first collects the participants' reaction times while not on antihistamines, and then gives them the dose of antihistamine. One hour later, he collects the participants' reaction times again.

Short answers
5. What two things must you normally specify in a variable declaration?
You must specify the variable type and an identifier.
int n; // type - int, identifier - n
6. What value is stored in uninitialized variables?
is a variable that is declared but is not set to a definite known value before it is used.
Algorithm workbench
3. Write assignment statements that perform the following operations with the variables a, b, and c.
a. Adds 2 to a and stores the result in b
b. Multiplies b times 4 and stores the result in a
c. Divides a by 3.14 and stores the result in b
d. Subtracts 8 from b and stores the result in a
Assignment statements that perform operations with the variables a, b, and c* (*Actually none of these operations involves the variable c at all... is this an error, or a 'trick answer'?):
b = a + 2
a = b * 4
b = a / 3.14
a = b – 8
4. Assume the variables result, w, x, y, and z are all integers, and that w = 5, x = 4, y = 8, and z = 2. What value will be stored in result in each of the following statements?
a. Set result = x + y
b. Set result = z * 2
c. Set result = y / x
d. Set result = y – z
result = x++ - y;
Answer -4
result = 4 – 8 = -4
result = ++w + y;
Answer
w = w + 1 = 5 + 1 = 6
result = 6 + 8 = 14
5. Write a pseudocode statement that declares the variable cost so it can hold real numbers.

For our Week 2 assignment, in Intermediate Algebra, we were asked to solve the problem number 68 on page 539 of Elementary and Intermediate Algebra. aside from completing the problem, we were also asked to write a two to three page paper while including the five given vocabulary words for the week. Please see the problem below:
Shipping restrictions. The accompanying graph shows all of the possibilities for the number of refrigerators and the number of TVs that will fit into an 18-wheeler.
a)
Write an inequality to describe this region.
b)
Will the truck hold 71 refrigerators and 118 TVs?
c)
Will the truck hold 51 refrigerators and 176 TVs?
Kindly consider the five given vocabulary words:
Solid line
Dashed line
Parallel
Linear inequality
Test point
In order to solve the problem, we need to be aware that the formula to solve any linear equation is y=mx+b. with the said, we can say that we have our y- intercept which is 330. (The ordered pair 0,330 demonstrates that the y coordinate is 330). Since we have our y- intercept, we will now discover what our slope is. The formula to determine any slope of a line is
m=y1- y2
x1-x2
M= 330-0
0-100
After performing division and simplifying, we have found that the slope of our line is -3.
a) Write an inequality to describe this region.

Solving Proportions
Proportions exist in the real world. For example, in finding out the price of a unit, or the population of a specific species. The first problem that we are working with states that “. Bear population. To estimate the size of the bear population on the Keweenaw Peninsula, conservationists captured, tagged, and released 50 bears. One year later, a random sample of 100 bears included only 2 tagged bears.What is the conservationist’s estimate of the size of the
bear population?(Dugolpolski, 2012)
In reading over the “Bear Population” #56 on page 437 (Dugolpolski, 2012), the concept of proportions allow the assumption that the ratio of originally tagged bears to the whole population is equal to the ratio of recaptured tagged bears to the size of the sample. The estimated solution, variables will be defined and rules for solving proportions are used.
The ratio of originally tagged bears to the whole population is 50/x.
The ratio of recaptured tagged bears to the sample size is 2/100.
50=2 This is the proportion set up and ready to solve. This is the step where we will cross multiply.
x 100 at this point. The extremes are 100 and 50. The means are x and 2
100(50)=2x
50002=2x2 Divide both sides by 2
X=2500 The bear population of Keweenaw Peninsula is estimated to be around 2500.
For the second problem of this...

a). What is YTM(i) for bond A and B? which one is highest?
Bond A: 1000 = 1001+i + 901+i2 + 80(1+i)3 + 70(1+i)4 + 60(1+i)5 + 600(1+i)5
i(A) = 0
Bond B: 1000 = 1001+i + 1001+i2 + 100(1+i)3 + 100(1+i)4 + 40(1+i)5 + 400(1+i)5
i(B) = - 0.04419415
Bond A has higher yield than Bond B. ( 0 > -0.044195)
b). Suppose i=0.05 for both bond A and B, which bond has higher price?
Bond A:
P = 1001+0.05 + 901+0.052 + 80(1+0.05)3 + 70(1+0.05)4 + 60(1+0.05)5 + 600(1+0.05)5 = $820.69
Bond B:
P = 1001+0.05 + 1001+0.052 + 100(1+0.05)3 + 100(1+0.05)4 + 40(1+0.05)5 + 400(1+0.05)5 = $699.35
c). Is there an identical i that i(t)=i(t+1)=i(t+2)=… that makes bond price for A and B identical?
1001+i + 901+i2 + 80(1+i)3 + 70(1+i)4 + 60(1+i)5 + 600(1+i)5
= 1001+i + 1001+i2 + 100(1+i)3 + 100(1+i)4 + 40(1+i)5 + 400(1+i)5
When i = 100%, both bond A and bond B have price equal to $107.50
Which bond is more risky?
If all the information is correct, bond A is more risky in year 1 to 4, and bond B is more risky at year 5 due to the CEO resign....

Week One Assignment
I will set up two ratios and show an appropriate variable and write the equation. First problem is: Bear population. To estimate the size of the bear population on the Keweenaw Peninsula, conservationists captured, tagged, and released 50 bears. One year later, a random sample of 100 bears included only 2 tagged bears. What is the conservationist's estimate of the size of the bear population?
In the Capture-Recapture method we notice that we are supposed to assume that the ratio of the original 50 tagged bears to the entire population is equal to the ratio of the recaptured tagged bears to the size of the sample (Dugopolski, 2012). First, we will set up the ratios.
Ratio of original tagged bears tot eh whole population is 50
X
The ratio of the recaptured tagged bears are 2
100
50 = 2 This is the proportion ready to solve. I will cross multiply
x 100 setting the extremes equal to the means.
100 (50) = 2x 100 and 50 are the two extremes, while x and 2 are the means.
5000 = 2x Divide both sides by 2.
