Engineers at a tire manufacturing company investigated the effect of a new rubber compound on the tire life of a certain brand o

f tires. From a sample of 16 tires, the engineers constructed a 99 percent confidence interval for the mean tire life, in miles, as 62,550±2,026. Suppose the company intends to claim a maximum tire life for advertising purposes. Based on the interval, of the following, which is the maximum plausible value for the mean tire life, in miles?

64,576 miles.

Explanation:

When the companies advertise their new products they want to present the product in the best possible light as possible. This is due to edging out the competition as in many products small details make a huge difference. The same is the case with the tires and their endurance. The longer way a set of tires takes you the better, since they are expensive product so changing them less often is very beneficial.

In this case, the interval for the mean tire life varies by 2,026 from 62,550, both up and down. The minimum will be 60,524 miles, while the maximum a tire can pass is 64,576. The company will of course go for the maximum value to make the product look as attractive and as good as possible to the customers.

Barron's has collected data on the top 1,000 financial advisers. Company A and Company B have many of their advisers on this lis
scoray [572]

Answer:

We'll start by putting into consideration, the large sample variance at the numerator.

Barron's Variance will be represented using 1 as the subscript.

i.e.

1 = $583 million

2 = $489 million

So,

0: 1²= 2²

: 1² ≠ 2²

=1² / 2²=

= $583 million² / $489 million²

= 583²/489²

= 1.42

Degrees of freedom 15 and 9

Using F table, area in tail is greater than 0.10.

Two-tail p-value is greater than .20

Exact p-value corresponding to F= 1.42 is .5874 (See F table)

p-value > .10

So,we do not reject 0.

We cannot conclude there is a statistically significant difference between the variances for the two companies.

List all the economic activities involved in each of the following businesses:
Bess [88]

Answer:

Selling cotton shirts at a high-street store:

Manufacture: First, the factory manufactures shirts using raw materials they’ve purchased from suppliers.

Quality control: The shirts go through quality control to check for defects and to ensure uniformity among all the shirts. Quality inspectors are paid to ensure that shirts are free of defects.

Packaging/transportation: After the quality control process, the factory packages the shirts and hires transportation services to transport the shirts to the retail outlet.  

Labeling: At a retail outlet, each type of shirt is valued and receives a price tag based on the discount that the storeowner decides to offer consumers.  

Selling: Consumers choose between many types of shirts and may decide to purchase the shirt based on the quality and price.

Selling hamburgers at a fast-food restaurant:

Buying the ingredients: Headquarters buy ingredients from meat suppliers.

Assembly process: A team of chefs starts the preparation by chopping and assembling all the ingredients. Another team of chefs makes the burgers, and the ingredients are ready for delivery. Chefs are paid to ensure burgers are prepared correctly and packaged to maximize shelf life.

Packaging: The packaging department packs the burger patties and hires a specialized transportation service to deliver the frozen patties to the restaurant.  

Selling: The restaurant prices the burgers and prepares them as customers order them. Customers can choose between this restaurant and another down the street.

Selling medicines at a drug store:

Manufacturing: A valid license holder manufactures the medicines. The manufacturer may hold the patent for certain drugs or may pay for the license to manufacture the drug.

Wholesalers: Wholesale dealers sell the medicines to pharmacies or other wholesalers.  

Selling: Pharmacies sell the medicines to consumers, who may have the choice to purchase other drugs, including generic drugs.

Selling gas at a gas station:

Production: The oil company has to drill underground to find oil. The operation is typically paid for by investors that hope to strike oil and sell the oil to a refinery.

Refining: The crude oil is then refined at a refinery, who purchases the oil from the drilling company.

Selling: The oil company sells the refined oil to gas stations, which sell the gas to consumers. Consumers have many choices for gasoline, so the market price is a buyers’ market.

What are two common causes of postoperative wound evisceration? why might these causes lead to wound evisceration?
earnstyle [38]

The two major causes of postoperative wound evisceration are as follows,

  • Post-surgery wound stress, which might involve something as simple as a cough or sneeze
  • Certain sutures may disintegrate too quickly, causing the wound to open.
  • The type of closure employed, may or may not have been beneficial for the incision.

What is evisceration?

Evisceration is a rare but serious surgical complication in which the surgical incision opens and the abdominal organs protrude or come out. Evisceration is a medical emergency that must be treated as such.

  • It can range from mild to severe, with the organs exposed and slightly protruding outside of the incision.
  • Intestines, for example, may leak from an abdominal incision.
  • This is usually considered a medical emergency.
  • If you notice tissue or organs emerging from a surgical site, call your doctor.
  • It is critical to keep the wound wet. Cover the opening and organs with a wet, sterile bandage or sheet while on your route to seek medical help or while waiting for EMS.
