Students and faculty alike are concerned about the cost of textbooks. A committee of both students and faculty searched the internet for appropriate books that would be available for less than $60. A random sample of 40 texts gave a mean of $65.12 with a standard deviation of $23.08. At the 5% level of significance, do the texts selected in the sample cost significantly more than the amount the committee considered appropriate?

(1) List all the information necessary for conducting the hypothesis test and state which

test you are doing.

(2) State the null and alternative hypotheses and whether you would use a right-tailed

test, a left-tailed test, or a two-tailed test.

(3) Sketch the critical reason, indicating on the sketch what the critical value(s) are.

(4) Determine the calculated z or t.

(6) Decide if you will Reject or Fail to Reject the Null Hypothesis.

(7) Interpret your conclusion in terms of the problem.

(8) If there are any questions to be answered in the problem, do so.

San Jose State University has experienced many different types of assaults and attacks over the recent years. Protecting students on campus day and night should be the main concern of the university. Risky Business believes that this is due to the poor lighting on campus to ensure that students feel safe. We believe that motion activated lighting on campus and in the parking garages will deter potential threats. Our project will dive into the scope baseline, project cost, and critical path.

Please provide who are the stakeholders in the above project plan and write 2 paragraph on how we will communicate with them in upgrading the lighting on campus and parking garage.

Don't simply list the strategies. You need to relate them to your project scenario. For example, if you say you plan to meet your stakeholders for communicating project status. You may explain how often you will meet, and what kind of info you plan to report as your milestone at monthly or quarterly meetings.

A child development specialist is interested in learning if a new learning program increases students’ memory. 15 Subjects learned a list of 50 words. Learning performance was measured using a recall test. Students were initially tested and then tested again after using the new program. Below is the number of words remembered by each student.

Student #                    Score 1                  Score 2

         1                              24                           26          

                2                              17                           24

                3                              32                           31

                4                              14                           17

                5                              16                           17

                6                              22                           25

                7                              26                           25

                8                              19                           24

                9                              19                           22

               10                             22                           23

Did the learning program significantly improve the student’s ability to recall words? Report standard error of means, df, obtained and critical t, and whether you would accept or reject the null hypothesis.

3 roadblocks to communication as Judging, Rejecting, and Blaming, Criticizing.

Identify and describe three roadblocks to communication. Now look at the list of ways to build bridges to communication in your textbook. For each of the three roadblocks to communication that you identified, pick one bridge to communication and tell how it could be an improvement to a roadblock.

Communication is a key part of healthy relationships between people and within an organization. What are some formal and informal channels of communication in a company or an organization? How do informal channels of communication differ from formal channels of communication?

Discuss an experience you had communicating with someone either in your personal or professional life. Describe the method of transmission of the message. Was it effective or were any elements misconstrued? Discuss in what ways the message was transmitted effectively and/or misconstrued. Explain why you felt it was transmitted effectively and/or misconstrued.

Effective communication is an essential factor to influence others; to express feelings and emotions; and to provide, receive, and exchange information. Current technology allows people to communicate in a wide variety of alternate ways including via instant messaging, text messaging, email etc. How does communication differ depending on the method used? How can one express feelings, emotions, tone, and intent clearly while using technology as opposed to face-to-face communication?

145&146&147. The potential of a silver electrode is measured relative to an Ag-AgCl electrode for the titration of 100.0 mL of 0.100 M Cl with 0.100 M Ag+. What is the potential after 75.00 mL of titrant is added. Eo = 0.799 V for Ag+, E = 0.197 V for the Ag-AgCl electrode and Ksp = 1.8 × 10−10.

A) 0.493 V

B) 1.070 V

C) 0.521 V

Let V be the set of all ordered pairs of real numbers. Consider the following addition and scalar multiplication operations V. Let u = (u1, u2) and v = (v1, v2).

Show that V is not a vector space.

• u ⊕ v = (u1 + v1 + 1, u2 + v2 + 1 )

• ku = (ku1 + k − 1, ku2 + k − 1)

1)Show that the zero vector is 0 = (−1, −1).

2)Find the additive inverse −u for u = (u1, u2). Note: is not (−u1, −u2), so don’t write that.

3)Show that V is not a vector space.

I have a collection of baseball cards, some from the 1984 season and some from other seasons. Considering only my valuable baseball cards, 60% of them are from 1984. Overall, 3% of my baseball cards are both valuable and from the 1984 season, and 38% of my cards are not valuable and not from the 1984 season. Fill out the table below
