Probability and Confidence Intervals Emily is trying to select a weight-loss plan to follow. She has narrowed her decision down to two different weight-loss plans. Recall the following formula for finding a confidence interval: Both weight loss plans make the following claim: Use the formula to find a confidence interval for the true percentage of participants who lost at least 10 pounds in the first month using each plan. "Fifty-eight percent of participants lost at least 10 pounds in the first month." Emily decides to dig further. She reviews the studies conducted by both companies and finds the following information on the amount of weight lost by participants in the first month of following the weight loss plan. Confidence interval for Plan A: Confidence interval for Plan B: Plan A Plan B Which plan should Emily choose? Use your confidence intervals to explain your answer. Lost less than 2 lbs 2 1 Lost 2-4 lbs 0 1 Lost 4-6 lbs 1 2 Lost 6-8 lbs 2 25 Lost 8-10 lbs 0 10 Lost over 10 lbs 7 53 Total Number of participants 12 92

Maglie Company manufactures two video game consoles: handheld and home. The handheld consoles are smaller and less expensive than the home consoles. The company only recently began producing the home model. Since the introduction of the new product, profits have been steadily declining. Management believes that the accounting system is not accurately allocating costs to products, particularly because sales of the new product have been increasing.

Management has asked you to investigate the cost allocation problem. You find that manufacturing overhead is currently assigned to products based on their direct labor costs. For your investigation, you have data from last year. Manufacturing overhead was $1,238,000 based on production of 280,000 handheld consoles and 93,000 home consoles. Direct labor and direct materials costs were as follows.

Management has determined that overhead costs are caused by three cost drivers. These drivers and their costs for last year are as follows.

Required:

a. How much overhead will be assigned to each product if these three cost drivers are used to allocate overhead? What is the total cost per unit produced for each product?

b. How much overhead will be assigned to each product if direct labor cost is used to allocate overhead? What is the total cost per unit produced for each product?

Tomato yields

Chris runs a CSA (“community sponsored agriculture”) farm, and they are trying to determine the optimal amount of “investment” in tomato seedlings. The table above shows the plot’s (expected) yield as a function of the number of tomato plants.

1. (a) Tabulate the MPK, in terms of pounds of tomatoes, as a function of the number of tomato plants.

2. (b) Assumetheinterestrateis7%(r=0.07),thepriceofaseedlingis$1,andtomatoessellfor$0.10/pound.

   Tomato plants are annuals (they live only one year) so d = 1. Calculate the user cost.

3. (c) Find the optimal amount of investment (the number of seedlings to plant).

4. (d) Repeat the calculation with:

   1. (i) A 5 percentage point increase in the interest rate, to 12%.

   2. (ii) A drop on the price of tomatoes, to $0.09/pound (r = 7%).

   3. (iii) A drop in the price of seedlings, to $0.90 (r = 7% and tomato price = $0.10).

   4. (iv) The introduction of a new variety of tomatoes with a 10% higher yield, regardless of the number

      planted (r = 7%, tomato price = $0.10 and seedling price = $1).

Please tell me how you would treat each rhythm from oxygen therapy to medication and if the patient will need cauterization and so on.

2. HR 122: Sinus Tach may require rapid response

Is this anxiety? Sepsis? Shock?

3. HR 160+ requires rapid response

Probably not atrial fibrillation …Responsive???

You are auditing the accounts receivable for ABC Company as of December 31, 2019 One of your procedures was to send positive confirmations to a sample of 50 accounts. Of those 50 confirmations, 40 have been positively confirmed without comments, 8 had minor differences that have been cleared satisfactorily. Two of the responses had the following comments:

a. “We never received these goods.”

b. “The balance of $1,000 was paid on December 15, 2018.”

For each of these comments, identify the steps that you would take to clear (resolve) them.
