Answer: D) We are 95% confident that the average taxi fare between Logan Airport and downtown Boston will fall between $20.51 and $24.21.

Explanation:

The Confidence interval allows one to speculate between which values the average of a population will be. In a 95% confidence interval, this means that we are 95% certain that the average value of a variable will be between the higher and lower limits set by the interval.

The 95% confidence interval here has an upper limit of  $24.2091 and a lower limit of $20.5051 for taxi fares from Logan Airport to downtown Boston. This means that with a 95% certainty, the taxi charge from Logan Airport to downtown Boston will be between these 2 charges so you can expect to pay an amount between them.

Colt1911 [192]

Answer:

A.C. Tech Manufacturing Appliances

Product Models to produce first, if management incorporates a short-run profit-maximizing strategy:

                                                 Small      Medium     Large

Selling price                             $430       $610          $1,210

Variable cost                            $270       $280         $530

Contribution                            $160        $330         $680

Fixed Costs:

Fixed manufacturing                 $40         $170          $270

Fixed selling & admin                $70         $75            $140

Unit Profit                                   $50         $85            $270

Demand in units                         150         170              150

Total profit                               $7,500     $14,450      $40,500

Machine hours/unit                     60           60             150

Total machine hours required 9,000      10,200        22,500

Unit profit per machine hour   $0.83      $1.42         $1.80

If management incorporates a short-run profit maximizing strategy, given maximum machine hours available, it should first produce the large model.

Explanation:

The large model offers better contribution per unit, better profit per unit and in total, and most importantly better profit per unit of hour (major constraint).

In making a limiting factor decision, the choice goes to the product model that produces more profit under the limiting constraint.

IgorC [24]

Answer:

(c) Interview customers to get their opinion about the checkout process  

Explanation:

Customers are those who buy goods or receive services from a business owner. Customers may sometimes not be the consumers because the customers may buy from the company and sell to other people to consume. The customers may also be the consumers at times when they consume what they bought. If customers do not buy from the business owners, they won't be consumers, thou consumers are gods in today's market and life wire of any business.Once customers are satisfied with the products and services provided to them by the company, they will continue to patronize the company and never substitute it for another company.Most companies start having problems or loose customers due to  nonsatisfaction of goods and services render by the company. Therefore, interviewing the customers to get their opinion about the checkout process is the best approach for gaining more insight into the problem because they are in the best position to state why they are not patronising the company's product again.

hjlf

Answer:

Therefore, indirect material indirect labor, and factory supplies are included in the variable costs, and the fixed costs include supervision taxes and depreciation expenses.

The mixed cost is a mix combination of both the variable cost and the fixed cost which includes some components of fixed cost and some components of variable cost. It is also known as semi-variable cost
