Answer:
Explanation:
Experiments were performed for 240 people, 60 people test positive.
Step 1: we calculate the sample proportion; p= 60/240= 0.25.
Step 2: calculate the standard error for the sample, which is the square root of sample proportion,p = p(1-p)/n, n=100
0.25(1-0.25)/100
= 0.04.
Step 3: calculate the test statistics; assuming the hypothesis test percentage is 25%
Then, we say 0.25-1=0.75
-0.75/0.04
= -1.875.
In particular, the sample results are -1.875 standard error.
Probability of Z is less than -1.875.
Look up it value in the Z table
Answer:
A) Shortage, B) Fall in Price
Explanation:
A] Market is at equilibrium where - downward sloping Market Demand (inversely related to price), & upward sloping Market Supply (directly related to price) - are equal & these curves intersect each other.
Above condition gives us equilibrium price & quantity.
If market price < equilibrium price, as given case 15 < 20. Then, supply being directly related to price is lesser, demand being inversely related to price is higher. So, there is a situation of excess demand, ie <u>shortage </u>(graphically denoted by distance between demand & supply curve at actual price below equilibrium price)
B] Dealers of hybrid vehicles increase imply increase in supply of these vehicles, rightwards shift in the supply curve. This creates excess supply ie surplus of them. It implies that competition among sellers lead to <u>fall in price </u>of these hybrid vehicles.
Answer:
Materials = 23,000 units
Conversion Costs = 23,000 units
Explanation:
Note that the weighted-average method is being used to calculate the equivalent units.
Using this method, we are interested only in calculating equivalent units in units that were completed and transferred and units of ending work in process.
<u>Calculation of equivalent units of production for Materials and Conversion Costs.</u>
Materials
Completed and transferred (20,000 units × 100%) 20,000
Ending Work In Process (5,000 units × 60%) 3,000
Equivalent units 23,000
Conversion Cost
Completed and transferred (20,000 units × 100%) 20,000
Ending Work In Process (5,000 units × 60%) 3,000
Equivalent units 23,000
Answer: B.) productivity at the work site has increased.
Explanation: The considerable increase in output at the work site while still maintaining the same number of workers and hours worked over the last six months shows that the productivity at the work site has increased. Productivity which is usually compares unit output to the rate of inout per unit. The effectiveness of the input or production effort is used to measure the degree of productivity. Therefore, when the output derived by maintiaing the same unit of input increases, then productivity has increased. If it decreases, then productivity has decreased.

working arrangement is a practice that allows employees to set varying working
hours depending on their personal needs. This modern approach in the workplace
enables employees to maximize their time both in and out of the office. It permits
employees to have a work-life balance. Employees are now able to spend more
quality time with their family and friends while being reinvigorated to work
effectively.</span>
