The formula for calculating the Confidence Interval is as follows:

Confidence Interval = x +- (z*s)/√N

Where:

x = mean = 10.36

z = taken from standard normal distribution table based on 95% confidence level = 1.96

s = standard deviation = 5.31

N = sample size = 30

Substituting know values on the equation:

Confidence Interval = 10.36 +- ( 1.96 * 5.31) / √30

Confidence Interval = 8.46 and 12.26

Hence the bill of lunch orders ranges from 8.46 to 12.26.

Gross pay:

  • consultant $4,000
  • computer programmer $3,300
  • administrator $2,800

Net pay:

  • consultant $2,767.98
  • computer programmer $2,295.48
  • administrator $1,993.98

Explanation:

                                           regular earnings     overtime    withholding  

                                                                                              allowances

Consultant                        $4,000 per week       N/A                2

Computer programmer          $60 per hour        1.5                  1

Administrator                          $50 per hour          2                  2

computer programmer worked 50 hours = ($60 x 40) + ($60 x 10 x 1.5) = $3,300

administrator worked 48 hours = ($50 x 40) + ($50 x 8 x 2) = $2,800

Social security taxes:

  • Consultant = 6% x $4,000 = $240                        
  • Computer programmer = 6% x $3,300 = $198        
  • Administrator = 6% x $2,800 = $168

Medicare taxes:

  • Consultant = 1.5% x $4,000 = $60                        
  • Computer programmer = 1.5% x $3,300 = $49.50        
  • Administrator = 1.5% x $2,800 = $42

Federal income taxes:

  • Consultant: amount subject to withholding = $4,000 - (2 x $75) = $3,850. Federal income taxes = $356.90 + [28% x ($3,850 - $1,796) = $932.02                        
  • Computer programmer = amount subject to withholding = $3,300 - (1 x $75) = $3,225. Federal income taxes = $356.90 + [28% x ($3,225 - $1,796) = $757.02            
  • Administrator = amount subject to withholding = $2,800 - (2 x $75) = $2,650. Federal income taxes = $356.90 + [28% x ($2,650 - $1,796) = $596.02  

Gross pay:

  • consultant $4,000
  • computer programmer $3,300
  • administrator $2,800

Net pay:

  • consultant $4,000 - ($240 + $60 + $932.02) = $2,767.98
  • computer programmer $3,300 - ($198 + $49.50 + $757.02) = $2,295.48
  • administrator $2,800 - ($168 + $42 + $596.02) = $1,993.98

Tim buys a house from Betty in 2011 for $200,000. Betty receives $185,000 and $15,000 goes to Mary, the real-estate agent. Betty
Step2247 [10]

Answer:

$15,000 

Explanation:

Gross domestic product is the sum of all final goods and services produced in an economy within a given period which is usually a year.

When calculating GDP, only items produced in the current year are added. The house had been sold in 2007. Adding the sale to the GDP in 2011 would lead to double counting.

It's only the amount paid to the agent that would be added to GDP.
