Answer:

(B) Statistic

Explanation:

A statistic is defined as a metric derived from (or that describes) a sample. As such, given a certain population (in the case of the question, <em>the population is the total number of new engines developed by the company</em>), a sample can be selected from the population (<em>the sample in the question is the 100 engines that are randomly selected</em>).

Any characteristic that describes the population is known as a parameter, whereas a characteristic that defines the sample is a statistic. In the question given, the average lifetime of 11 years was derived from the sample of 100 engines as is thus a statistic.

Calculate Payroll An employee earns $44 per hour and 1.5 times that rate for all hours in excess of 40 hours per week. Assume th
Ket [755]

Answer:

The correct answer for option (a) is $3,080 and for option (b) is $2,141.

Explanation:

(a). Current pay = $44

After 40 hours, Pay = $44 × 1.5 = $66

So, we can calculate the gross pay by using following formula:

Gross pay = (40 hours × $44 ) + (20 hours × $66)

= $1,760 + $1,320

= $3,080

(b).

Security Tax = Gross pay × 6% =  $3,080 × 6% = $184.8

Medicare Tax = Gross pay × 1.5% =  $3,080 × 1.5% = $46.2

Federal Income Tax = $708

So, we can calculate the net pay by using following formula:

Net Pay = $3,080 - $184.8 - $46.2 - $708

= $2,141
