Can someone send me a screen shot of how to input this into SPSS data and variable view to obtain the information provided below?

Question 1

The nominal scale of measurement is used to measure academic program in this example because data collected for the students is nothing but the names of their major subjects or classes and their status of mood whether they are nervous or excited.

Question 2

The nominal scale of measurement is used to measure feeling about PSY 3002 because the feeling is explained by two categories such as nervous and excited.

Question 3

This scenario required a Chi-square test of independence between two categorical variables. For this scenario, two categories are given as major subject and feeling. Here, we have to check the hypothesis whether the two categorical variables major subject of student and feeling of a student are independent of each other or not.

Question 4

For this scenario, the null and alternative hypotheses are given as below:

Null hypothesis: H₀: The two categorical variables major subject of student and the feeling of the student are independent of each other.

Alternative hypothesis: H_a: The two categorical variables major subject of student and feeling of student are not independent from each other.

We can also write these hypotheses as below:

Null hypothesis: H₀: There is no any relationship between two categorical variables such as major subject of student and feeling of student.

Alternative hypothesis: H_a: There is a relationship between the two categorical variables such as major subject of student and feeling of student.

Question 5

The Chi square test statistic is given as 16.94235589.

Question 6

Number of rows = r = 2

Number of columns = c = 2

Degrees of freedom = (r – 1)*(c – 1) = (2 – 1)*(2 – 1) = 1*1 = 1

Degrees of freedom = 1

Question 7

P-value = 0.0000385

(by using Chi square table or excel)

Question 8

Reject the null hypothesis because p-value is less than alpha value 0.05.

Question 9

Yes, results are statistically significant because p-value for this test is given as 0.0000385 which is less than alpha value 0.05.

Question 10

There is sufficient evidence to conclude that there is a relationship between the two categorical variables such as major subject of student and feeling of student.

There is sufficient evidence to conclude that two categorical variables major subject of student and feeling of student are not independent from each other.

1. Ceramics often fracture below their theoretical strength due to cracks which concentrate the applied stress.

2. The interstitial diffusion coefficient for a small atom diffusing in a metal is usually larger than its diffusion coefficient via a vacancy mechanism.

3. BCC, HCP, FCC are all Bravais lattices belonging to the cubic crystal system.

4. The larger the number of slip systems available to a metal, the easier it is to deform.

5. HCP has an "abab" stacking sequence, FCC has an "abcabc" stacking sequence.

6. Dislocations move most easily in a crystal along the highest density planes along the lowest density direction.

7. There are 14 Bravais lattices, each of which belongs to one of the 7 crystal systems.

8. Elastic deformation results from the breaking and reforming of bonds.

9. Thermal expansion in crystalline materials is the result of an asymmetry in the repulsive and attractive force curves between pairs of atoms.

10.Graphite and diamond are two different phases of carbon.

Imagine you wanted to design a quasi-experiment to study the hypothesis that Changing the start of the day in high school start time to 8:30 a.m. or later causes teens to suffer less depression. Imagine that there are four public high schools, all in the same area of the country, that are willing to participate in this study. Currently, they all start between 7:20 a.m. and 7:35 a.m., but in fact, two of the high schools are already planning to change their starting times next fall.

1.Why might it be more practical to conduct a quasi-experiment on this question, rather than a true experiment? (2 pts)

2. Using one of the designs below, design a quasi-experiment to research this question. Clearly identify which study type you are using and clearly demonstrate knowledge of the study design. (4 pts)

•Nonequivalent control group design (posttest-only)

•Nonequivalent control group design (pretest/posttest).

•Interrupted time-series design

•Nonequivalent control group interrupted time-series design

Write a recursive function named multiply that takes two positive integers as parameters and returns the product of those two numbers (the result from multiplying them together). Your program should not use multiplication - it should find the result by using only addition. To get your thinking on the right track:

7 * 4 = 7 + (7 * 3)

7 * 3 = 7 + (7 * 2)

7 * 2 = 7 + (7 * 1)

7 * 1 = 7

So, 7 * 4 = 7 + (7 + (7 + (7)))

The file must be named: multiply.py Must use Python, NOT C++

Two charges, +5 µC and +17 µC, are fixed 1 m apart, with the second one to the right. Find the magnitude and direction of the net force (in N) on a −7 nC charge when placed at the following locations. (a) halfway between the two magnitude N direction (b) half a meter to the left of the +5 µC charge magnitude N direction (c) half a meter above the +17 µC charge in a direction perpendicular to the line joining the two fixed charges (Assume this line is the x-axis with the +x-direction toward the right. Indicate the direction of the force in degrees counterclockwise from the +x-axis.) magnitude N direction ° counterclockwise from the +x-axis
