The Wall Street Journal reported that automobile crashes cost the United States $162 billion annually (The Wall Street Journal,

March 5, 2008). The average cost per person for crashes in the Tampa, Florida, area was reported to be $1599. Suppose this average cost was based on a sample of 50 persons who had been involved in car crashes and that the population standard deviation is σ = $600. What is the margin of error for a 95% confidence interval? Round your answer to two decimal places.

Answer:

Error = 166.308459

Explanation:

Given that,

Standard deviation (SD) = $600

Sample (n) = 50 persons

Error(E) = ?

For a 95% confidence interval,

Z-value from the z-table is 1.959963985

E=\frac{z\times SD}{\sqrt{n}}

E=\frac{1.959963985\times 600}{\sqrt{50}}

E=\frac{1,175.97839}{7.07106781}

         = 166.308459

Therefore, the margin of error for a 95% confidence interval is 166.308459.

Airida [17]

Answer:

Results are below.

Explanation:

<u>To calculate the activities rate, we need to use the following formula:</u>

Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base

Designing= 444,000/13,000= $34.15 per designer hour

Sizing and cutting= 4,210,000 / 169,000= $24.91 per machine hour

Stitching and trimming= 1,490,000 / 75,500= $19.73 per labor hour

Wrapping and packing= 332,000 / 32,000= $10.38 per finished unit

5) A car rental company offers two plans for one way rentals. Plan I charges $36 per day and 17 cents per mile. Plan II charges
Rom4ik [11]

Answer:

a. Plan I is better is we drive 300 miles in a day.

b. 150 miles.

Explanation:

a. if mileage is 300 then rental charges will be,

Plan I : $36 + 17 cents * miles

$36 + 0.17 * 300 = $41.10.

Plan II : $24 + 25 cents * miles

$24 + 0.25 * 300 = $99.00

Plan I total cost for 300 miles is $41.10 whereas Plan II total cost for 300 miles is $99.00. Plan I is better plan and cost effective.

b. For mileage (m) calculation we will use equation;

Plan I = Plan II

$36 + 0.17m = $24 +0.25m

0.25m - 0.17m = $36 - $24

m = $12 / 0.08

m = 150 miles.

Sergeu [11.5K]

Answer:

$11 billion annually.

Explanation:

Firms carried out assessments based on their daily activities as well as employee assessment.

Employees in firms are assessed based on their productivity level, rate at which they are absent from work as well as their turnover rate in the firm.

Low productivity can be defined as a decrease in the production capacity of a firm due to the inefficiency of workers.

Absenteeism can be defined as when a person is not present at work. This may be due to genuine or deliberate reasons.

Employee turnover can be defined as the number of employees who leave a firm and are replaced with new employees.

Low productivity, consistent absenteeism and employee turnover rates are said to cause firms to lose a lot of money due to:

a. Payment of salary for absent workers

b. Having to find replacement for absent staffs.

c. Low productivity due to lack of or absent staffs.

It is estimated that firms lose $11 billion annually in productivity, absenteeism, and employee turnover due to caring for aging parents.
