What is the probability that at most 12 students will go on to graduate? Round your answer to 4 decimal places.

b.

What is the probability that at at least 15 students will go on to graduate? Round your answer to 4 decimal places.

Instructions:

Find a company online where you would like to apply for a job.

Research the company and write a description using the guidelines below.

Answer the question: Why do you want to work for this company?

Do Your Homework

When I say, “homework” I am referring to research and preparation in three key areas:

Know yourself

Know the company

Know the position and the department

Know Yourself

Before you talk to employers, or even network for positions, you need to have a strong grasp of what you can offer them. (What’s the return on investment you provide to the employer?)

You should be able to talk about your strengths and your accomplishments, and to readily give concrete answers to questions such as “What are your greatest strengths?” “Why should we hire you?” and “Tell me about yourself” as well as “What do you know about us? And “Why do you want to work here?

Know the Company

Get to know the companies you will be talking to (or talking about, if networking). When you know details about them, their culture, their goals, their products, and their challenges, you are then able to talk about yourself and your fit into the company.

Google the company and read all you can. Visit their company website to learn more about them.

Know the Position and the Department

In this economy, there is no room for shopping for “any job you find me qualified for.” Instead, you need to know where you would fit into the company, whether there is a current advertised opening or not.

Putting it all Together

Once you have done all your pre-interview homework, you will never again find yourself blundering on critical questions like, “Why do you want to work here?” Instead, you will be prepared to talk knowledgeably about the company and position, why they interest you, and how you will fit in with your skill set, personality and experience.

A​ college's data about the incoming freshmen indicates that the mean of their high school GPAs was 3.4 with a standard deviation of 0.30. the distribution was roughly​ mound-shaped and only slightly skewed. The students are randomly assigned to freshman writing seminars in groups of 25. What might the mean GPA of one of these seminar groups​ be? Describe the appropriate sampling distribution​ model, including​ shape, center, and​ spread, with attention to assumptions and conditions. Make a sketch using the​ 68-95-99.7 Rule.

10. A school administrator thinks that teacher absences are equally probable for each day of the week. A co-worker does not agree and gathers data from last year and reports the absences for the day of the week in this table: Monday (46) Tuesday (47) Wednesday (40 )Thursday (50) Friday (67) Test that the days of the week have an equal probability of absences at the 0.10 level of significance.

The average number of graduates for a school district has been 250 per year with a standard deviation of 30. What is the probability that the number of graduates next year will be:

a. Less than 220

b. Less than 325

c. Less than 285

d. More than 238

e. More than 300

f. More than 325

A dean of a business school is interested in determining whether the mean grade point average (GPA) of students is different from 3.04. The population standard deviation is 0.41. A random sample of 200 students indicates a sample mean GPA of 2.94. A test is conducted at the 0.05 level of significance to determine whether the mean grade point average (GPA) of students is different from 3.04. What is the test statistic value in this test?

Select one:

a. -3.449

b. +0.244

c. -0.244

d. +3.449

The Somerton High School PTO is creating a website that will allow students to quickly look up their homework assignments. The database supporting this website will keep track of departments, teachers, classes, and assignments. Each department has a name such as “Math”, “Science”, or “English” and each teacher is a member of a single department. For each teacher, the database should store a title (“Mr.”, “Ms.”, “Dr.”, etc), first name, middle initial, last name, office phone number, and e-mail address. Each class is taught by a one teacher; for each class, the database should store a name, description, meeting period (for example, seventh period), and room number. Finally, each class has multiple assignments. For each assignment, the database should store the date assigned, the date due, and a text description of the work assigned. Obviously, the database also needs to remember which class each assignment is for, and which teacher teaches each class.

A. Design a database to hold all this information. You may create synthetic keys as necessary or convenient.

B. Write outline notation and justify the primary key you have chosen for each table in the database.

C. In Access, create all the necessary tables for this database, and choose a reasonable datatype for each attribute. Assume phone numbers are in standard US format. If you use any “AutoNumber” synthetic primary keys, note that a matching foreign key should have a datatype of “Number”, with a field length of “Long integer”. Create all necessary relations between the tables and enforce referential integrity. You do not have to enter any data or create any forms. Create a “Documenter” report for the database.

1.            The completion times for the government exam used for entrance into Officer Candidate School is uniformly distributed between 85 minutes and 145 minutes.

                A.            What is the probability someone finishes the exam between 95 and 120 minutes?

                B.            What is the probability it takes a candidate at least 110 minutes to finish the exam?

Make sure you round to 4 decimal places where appropriate.

2.            The average daily commuting distance for a San Diegan is 31 miles with a standard deviation of 5.8 miles. If commuting distances are normally distributed:

                A.            What is the probability that a person commutes at most 35 miles?

                B.            What is the probability that a person commute is between 25 and 38 miles?

C.            What would someone have to commute to be in the top 6% of longest commutes (Where does the Top 6% start)?

Make sure you round to 4 decimal places where appropriate.

When you answer the question put the 5 answers in this order and label like this:

Previous Question:

The mean store for an exit text at an urban high school examination was 68% with a standard deviation of 3. Given these results, what percentage of students fall under the mean?

25%

50%

60%

75%

Using the same data from the question above, what scores will fall within one standard deviation above and one standard deviation below the mean?

All applicants to medical school are required to take an entrance exam. Historically, scores on the exam are known to be normally distributed with mean 80 and standard deviation 4. This year, we observe that a sample of 16 applicants obtains an average score of 78.67. Does this provide evidence that the average of all this year's applicants is less than 80? To answer this question, we do a hypothesis test using a significance level of 0.05.

Check all of the following statements that are correct (more than one alternative can be correct). Also, let ?μ be the mean of all this year's applicants.

Group of answer choices

a. The null hypothesis is ?0:?=H0:μ= 80

b. The alternative hypothesis includes an > sign

c. The value of the test statistic is z = -1.83

d. The p-value for this hypothesis test is 0.092

e. For this hypothesis test, we fail to reject ?0
