Question 18 options:

Question 19 (1 point)

Saved

A random sample of eight elementary school students is selected. What is the probability that their average height is between 122 cm and 123 cm?

Question 19 options:

You have chosen biology as your college major because you would like to be a medical doctor. However, you find that the probability of being accepted to medical school is about 20 percent. If you are accepted to medical school, then your starting salary when you graduate will be $250,000 per year. However, if you are not accepted, then you would choose to work in a zoo, where you will earn $39,000 per year. Without considering the additional years you would spend in school if you study medicine or the time value of money.

1. What is your expected starting salary?

2. What is the standard deviation of that starting salary?

Discuss your experiences with cyber-bullying – either a personal experience or one you know of from peers or the media. How did the different roles (victim, bully, bully victim, bystanders, and “toadies”) present themselves in this experience?

Then, imagine you are on the school board and a vocal advocate against bullying. You have been asked to design a program that addresses bullying in your school. How would you approach this task? Describe four factors involved in a multifaceted school-based approach to cyber-bulling prevention. What specific components would be included in your program? Be sure to look at community factors as well as family considerations. Be specific and explain your answers.

Question 5 (1 point)
A high school math teacher believes that male and female students who graduated from the school perform equally well on SAT math test. She randomly chooses 10 male students and 10 female students who graduated from this school. The following are the SAT math scores of the 20 students:

Male: 23, 30, 27, 29, 22, 34, 36, 28, 28, 31
Female: 22, 33, 30, 28, 28, 31, 34, 25, 29, 21

A recent survey showed that in a sample of 100 elementary school teachers, 15 were single. In a sample of 180 high school teachers, 36 were single. Is the proportion of high school teachers who were single greater than the proportion of elementary teachers who were single? Use α = 0.01.a) State the hypotheses that need to be tested (using proper notation)

b) Calculate the pooled estimate of p.

c) Calculate the test statistic.

d) Calculate the P-value OR critical value.

e) Make a conclusion(IN CONTEXT) using the connection between the P-value and alpha level OR test statistic and critical value.

Conch Republic Electronics Conch Republic Electronics is a midsized electronics manufacturer located in Key West, Florida. The company president is Shelly Couts, who inherited the company. The company originally repaired radios and other household appliances when it was founded over 70 years ago. Over the years, the company has expanded, and it is now a reputable manufacturer of various specialty electronic items. Jay McCanless, a recent MBA graduate, had been hired by the company in its finance department. One of the major revenue-producing items manufactured by Conch Republic is a smart phone. Conch Republic currently has one smart phone model on the market and sales have been excellent. The smart phone is a unique item in that it comes in a variety of tropical colors and is preprogrammed to play Jimmy Buffett music. However, as with any electronic item, technology changes rapidly, and the current smart phone has limited features in comparison with newer models. Conch Republic spent $750,000 to develop a prototype for a new smart phone that has all the features of the existing one but adds new features such as wifi tethering. The company has spent a further $200,000 for a marketing study to determine the expected sales figures for the new smart phone. Conch Republic can manufacture the new smart phone for $205 each in variable costs. Fixed costs for the operation are estimated to run $5.1 million per year. The estimated sales volume is 64,000, 106,000, 87,000, 78,000, and 54,000 per year for the next five years, respectively. The unit price of the new smart phone will be $485. The necessary equipment can be purchased for $34.5 million and will be depreciated on a seven-year MACRS schedule. It is believed the value of the equipment in five years will be $5.5 million. Net working capital for the smart phones will be 20 percent of sales and will occur with the timing of the cash flows for the year (i.e., there is no initial outlay for NWC). Changes in NWC will thus first occur in Year 1 with the first year?s sales. Conch Republic has a 35 percent corporate tax rate and a required rate of return of 12 percent. Shelly has asked Jay to prepare a report that answers the following questions: Questions

5. How sensitive is the NPV to changes in the price of the new smart phone?

6. How sensitive is the NPV to changes in the quantity sold?

7. Should Conch Republic produce the new smart phone?

8. Suppose Conch Republic loses sales on other models because of the introduction of the new model. How would this affect your analysis?
