A manufacturer of smartphones is interested in designing a new phone around the way a typical customer would use it. One of the most important characteristics for any smartphone is battery life since every activity on a smartphone draws power from the battery in some way. This is especially true for those who use their phones heavily for texting, social media, gaming, etc.

In a marketing research survey, the manufacturer asked a random sample of 25 smartphone owners who consider themselves "heavy users" to run an app on their phone that would record the time the phone is used for various activities (but, for privacy reasons, not record what that activity was).

The company decides to first examine the total minutes used in all activities. The sample mean number of minutes of total use from the 25 users was 122.5, with a standard deviation of 20.6 minutes. Find the upper bound of a 90% confidence interval for the true mean total time that smartphones are used by the population of "heavy users" to one decimal place. Take all calculations toward the answer to three (3) decimal places.

12/31/17 Co estimates 4% of its outstanding $300,000 in receivables will be uncollectable. ADA already has a credit balance of $1000.

1. Make the JE to record estimated uncollectable receivables.

2. On 1/31/18 $2000 of receivables is determined to be uncollectable. Make JE.

3. What is ADA balance 2/1/18?

4. What are net (or cash) receivables on 2/1/18?

5. Are the two net receivable figures, from both before and after 1/31 write off different in value? Why or why not?

6. On 2/3/18 Co learns the $2000 it had written off is now paid in full.

7. 2/15/18 Co sells $100,000 of receivables to Factor Co at a 5% service charge.

8. 3/3/18 Co sells $1000 of goods to customer who paid with Visa or Mastercard where the card company charges 5% fee.

1. Co accepts a $10,000 Note in settlement from a customer who already owes Co $10,000.

Please answer all parts thank you.

Bad company's stock price is $35, and it has 2.0 million shares outstanding. You believe that if you buy the company and replace its management its value will increase by 16%. Assume that Bad has a poison pill with a 20% triggered all target shareholders-other than the acquirer-will be able to buy one new share in Bad for each share they own as an 80% discount? Assume that the price remains at 35 while you are acquiring your shares. If Bad's management decides to resist your buyout attempt you cross the 20% threshold of ownership.

A. how many new shares will be issued and at what price?

B. What will happen to your percentage ownership of Bad?

C. What will happen to the price of your shares of Bad?

D. Do you lose or gain from triggering the poison pill? If you lose, where does the loss go (who benefits)? If you gain, where does the gain come from (who loses)?

E. Every other shareholder in the target firm gains________ per share?

1- How would you benefit from an application of PM techniques in a project you may have been involved with? Consider how you would define the specific tasks and their respective durations in this "project." What were the goals of the project? What con- straints were imposed on the project managers?

3- Consider the relationship between a project team and the functional parts of an organ-ization. Who should have responsibility for approving specific tasks? If an engineer- ing task goes beyond its proposed duration and budget, who is responsible-the director of engineering or the project manager? In general, how do you think a com- pany that is functionally organized should deal with projects?

4- Suppose that your company has over a dozen projects to choose from-but can select only a limited few. What criteria would you suggest for ranking the projects? How would you ultimately decide which projects to select?

what can we learn from Health Psychology and what it tells us about health-based behaviors? Choose some of the concepts that you feel are most compelling related to Health Psychology and discuss why you feel they are important and the role they play in the overall health of people. Your Discussion should be 3-4 paragraphs in length, detailing your thoughts and position using 2-3 readings references for support. Also be sure to pose 1-2 well thought out questions from which your colleagues can formulate a response or generate further discussion.

When making decisions, we may encounter some barriers that stop us from making rational decisions. However, it is important to make our decisions rationally.

(a) Discuss the five (5) barriers to rationality.

(b) Based on a decision you have made, explain how you can utilise the six (6) steps mentioned in unit 5 to make a decision rationally.

The Earth's magnetic field protects us from cosmic rays, which are extremely-high-energy subatomic particles generated by esoteric processes in interesting parts of the universe. To get an idea of how this protection might happen, pretend the earth's magnetic field has a constant value of 5.0 x 10^-5 T (northward) from the ground up to a height of 50 km.

(a) Suppose a high-energy proton (charge +1.6 x 10^-19 C, mass 1.67 x 10^-27 kg) hits the top of the earths magnetic field at some high velocity, call it v, straight. On the diagram, sketch the path it would follow.

(b) For what initial speed v would the proton just make it to the earth's surface?

(c) When the proton from part (b) reaches the surface, what is its velocity (magnitude and direction)?

(d) Would protons moving faster than your answer to (b) reach the ground? Would slower ones hit the ground?

(e) What does happen to the protons that don't hit the ground?
