In a certain state's lottery, 45 balls numbered 1 through 45 are placed in a machine and six of them are drawn at random. If the six numbers drawn match the numbers that a player had chosen, the player wins
$1,000,000. In this lottery, the order in which the numbers are drawn does not matter.
Compute the probability that you win the million-dollar prize if you purchase a single lottery ticket. Write your answer as a reduced fraction.

Respond to the Exercises on Green and Salkind
Part 1:
Green & Salkind:
Lesson 25, Exercises 1–3 This is the data -->Module 3(1).zip
The following helpful tips are numbered to correspond with
the exercise number to which they refer (a dash indicates that no tips are
needed):
1.
Use Tukey’s test
as the post hoc test for ANOVAs in PSYC 355. Be sure to check this box when you
run analyses. For letters a–d, instead of identifying these values on your
output, as the text states, write them into your Word file as written answers for #1 a, b, c, and d.
(2 pts for output and 2 pts each for a–d)
2.
---------- (3 pts)
3.
Remember to put your dependent variable in the
“variable” box, and your independent, or grouping, variables in the “category
axis” box. (3 pts)
Part 2:
1. Sixth grade students who struggle
with similar social difficulties at school and home are randomly assigned to 1 of
3 group therapy conditions in order to improve their social skills: manualized
cognitive-behavioral therapy (MCBT), non-manualized cognitive-behavioral
therapy (NMCBT), and talk therapy (T). Following 2 months of therapy, the
students are assessed on a standardized measure of social skills. On this
instrument, scores range from 0–65, and higher scores indicate better or
improved social skills, while lower scores indicate social skills that need
improvement. These scores are shown in the table below. Conduct a one-way ANOVA to determine how effective these 3 therapy
conditions are at improving social skills.
The steps will be the same as the
ones you have been practicing in Part 1 of the assignment—the only difference
is that you are now responsible for creating the data file as well. Remember to
name and define your variables under the “Variable View,” then return to the
“Data View” to enter the data. (3 pts)

2. What is the F ratio for the therapy
group main effect? (3 pts)
3. What is the effect size for the overall effect of therapy type on social skills
scores? According to general conventions, is this effect small, medium, or
large? (3 pts)
4. Write an APA-style Results section
describing the outcome. All homework “Results sections” must follow the example
given in the Course Content document “Writing Results of Statistical Tests in Current
APA Format” (Note: you do not have to refer to a figure). (3 pts)
5. The
null hypothesis for this test can be written as follows: “There is no difference
among the mean social skills scores across all three therapy conditions.” Based
on your results, should this hypothesis be rejected or retained, and why? Write
your answer in sentence form. (3 pts)
Part 3: Cumulative
Homework
1. In a study of the relationship between violent pornography and
aggression toward women, 16 male volunteers are selected and randomly assigned
to 1 of 2 groups. One group views a violent, sexually explicit film, and the
other group sees a nature film. A test to measure aggressive feelings toward
women is then administered to all participants. (High scores = high aggressive
feelings.) Is there a significant difference between the groups on feelings of
aggression towards women? Choose the correct test to analyze this question, set
up the SPSS file, and run the analysis. Follow the directions under the table
below.

How Far Will You Travel Portfolio 2 and 3 Dimensional Vectors Questions
Suppose that you plan to take a trip to your dream destination. You would like to know the shortest distance between your starting point and your destination. When calculating distances on a plane, you need only consider two dimensions because you are on a flat surface. However, when finding distances between two points on earth, you must take into the account the curvature of a sphere. In this portfolio, you will extend your knowledge of two-dimensional vectors to three-dimensional vectors in order to find the shortest distance between two points on the surface of earth.

1. Write as a single power of 2. Carefully show each step of your work.2. Police departments find it very useful to be able to approximate driving speeds in skidding accidents. If the road surface is wet concrete the function is S(x) = is used, where S(x) is the speed of the car in miles per hour and x is the distance skidded in feet.a. Fill out the table for each of the distances shown below. Round to the nearest whole number:b. Find the distance the car will skid if the speed of the car is 60 miles per hour.Round to two decimal places.3. Complex numbers are used by engineers and physicists to measure electrical circuits. To measure voltage, they use the formula E = I • Z, where E is voltage in volts, I is the current in amps, and Z is impedance, or resistance, in ohms.a. Find the voltage for an electrical circuit if the current is 3 - 4i amps and the impedance is 2 + i ohms. Simplify your answer completely. b. Find the Impedance for an electrical circuit if the voltage is 18 - 24i and the current is 6 - 3i amps. Simplify your answer completely.(please show all work)
