Females, it is said, make 70 cents to the dollar in the United States. To investigate this phenomenon, you collect data on weekl

y earnings from 1,744 individuals, 850 females and 894 males. Next, you calculate their average weekly earnings and find that the females in your sample earned $346.98, while the males made $517.70.
Required:
Calculate the female earnings in percent of the male earnings. How would you test whether or not this difference is statistically significant?

Answer:

67%

Test for 2 Independent means

Explanation:

Given that:

Average Female earning per week in sample = $346.98

Average Male earning per week in sample = $517.70

Female earning in percent of male earning :

(Female earning / male earning) × 100%

(346.98 / 517.70) * 100%

0.6702337 * 100%

67.02%

= 67%

Testing whether or not the difference in weekly earning by males and female can be conducted by testing the difference in sample means of both males and females by taking the two different samples as being independent.

Usually :

Null hypothesis : H0 : m1 - m2 = 0

Alternative hypothesis : H1 : m1 - m2 ≠ 0

The factors that affect the price elasticity of supply include: Instructions: You may select more than one answer.
bearhunter [10]

Answer:

The correct answer is letter "A", "B", and "D": the availability of inputs; the flexibility of the production process; time needed to adjust to changes in price.

Explanation:

Price elasticity of supply reflects the changes in supply after a change in prices. The price elasticity of supply is calculated dividing the percentage in the change of quantity supplied by the percentage in the change of price. If the result is equal or greater than one (1) the supply of that good is elastic. If the result is lower than one (1), then the supply is inelastic.

Three main factors determine the price elasticity of supply which are <em>the amount of inventory or raw material in the industry, the capacity to increase or decrease the production, </em>and <em>the time needed to produce the good to be offered based on the price fluctuations.</em>

Convert the following temperature to Celsius scale (a) 450 k, (b) 273 k, (c) 73 k.​
masya89 [10]

Answer: See explanation

Explanation:

To convert to Celcius scale from Kelvin, the formula to use is:

Temperature in Celcius = Temperature in Kelvin - 273

a. 450k

Temperature in Celcius = Temperature in Kelvin - 273

= 450 - 273

= 177°Celcius

(b) 273 k

Temperature in Celcius = Temperature in Kelvin - 273

= 273 - 273

= 0°C

(c) 73 k

Temperature in Celcius = Temperature in Kelvin - 273

= 73 - 273

= -200°C

A manufacturer has an estimated practical capacity of 90,000 machine hours, and each unit requires two machine hours. The follow
nata0808 [166]

Answer:

Of the following factors, the manufacturer's production volume variance is most likely to have been caused by:

D. Temporary employment of workers with lower skill levels than originally anticipated.

Explanation:

a) Data and Calculations:

Estimated practical capacity = 90,000 machine hours

Machine hours per unit = 2

Estimated production units based on capacity = 45,000 (90,000/2)

                                                   Budgeted          Actual

Variable overhead =                 $200,000      $240,000

Actual fixed overhead =           $450,000      $442,000

Machine hours                             90,000           88,000

Units produced                            45,000           42,000

Estimated units to be produced based on standard machine hour

= 44,000 units (88,000/2)

Variance between standard units to be produced and actual = 2,000 (44,000 - 42,000) Unfavorable
