What are the causes of metabolic alkalosis? Select the correct answer below: Too much CO2 is eliminated, dropping the CO2 pressure below 38 torr and resulting in a rise in blood pH. This can be caused by hyperventilation, fever, excessive exercise, or reactions to certain drugs. The body eliminates too much acid or produces too much base for the renal system to compensate, resulting in a rise in blood pH. Breathing difficulty or lung problems that reduce the ability to remove CO2, resulting in a CO2 pressure over 42 torr, so acidic protons are not removed and the pH drops. Changes in the H+ or HCO3- concentrations that result in the pH dropping. It can be brought on by diabetes, kidney disease, diarrhea or vomiting, or inadequate oxygen.

The sample consisted of 56 "hot spots"-areas of the city with a high crime rate but not necessarily a high drug crime rate. In Method 1, the new program will be implemented in half of the 56 hot spots (selected at random); the othier half will not implement the program (the "no treatment" group). In Method 2, the 56 hot spots will be divided into four groups based on the level of drug crimes - very high drug crime rate ( 10 hot spots), high rate ( 8 hot spots), moderate rate ( 26 hot spots), and low rate ( 12 hot spots). In each group, half the hot spots will be randomly assigned the new crime prevention program and the other half no treatment. For both methods, after several weeks the crime rates in the hot spots where the program was implemented will be compared with those with no treatment. Complete parts a through d below. a. Identify the data collection method for Method 1. Choose the correct answer below. A. Random sample B. Published source C. Designed experiment D. Observational study b.

Special-Order Decision The Cool Can Company manufactures drink kiosies and has been approached by a new customer with an offer to purchase 15,000 units at a per-unit price of 9.00. The new customer is geographically separated from Cool Can's other customers, and existing sales will not be affected. Cool Can normally produces 85,000 units but plans to produce and sell only 65,000 in the coming year. The normal sales price is 16 per unit. Unit cost information is as follows: Direct materials 3.10 Direct labor 2.75 Variable overhead 1.00 Fixed overhead 1.80 Total 8.65 If Cool Can accepts the order, no fixed manufacturing activities will be affected because there is sufficient excess capacity. 1. What are the alternatives for Cool Can? 2. Conceptual Connection: Should Cool Can accept the special order? By how much will operating income increase or decrease if the order is accepted? 3. Conceptual Connection: Briefly explain the significance of the statement in the exercise that "existing sales will not be affected" (by the special sale).
