Answer:
Option D. We are 95% confident that the mean amount spent on electric service among the 160 households is between $151 and $216.
Explanation:
A confidence interval is a range of values, derived from the sample statistics, which may include the value of an unknown population parameter.
A 95% confidence interval indicates that between 152 of 160 samples (95%) of the same population will produce confidence intervals that will contain the population parameter.
It also means that we have a 95% confidence that the average (average amount) is among the resulting amounts obtained.
Logically, option "D" is missing the final part. This would be: D. We are 95% confident that the mean amount spent on electric service among the 160 households is between $ 15.
This is the only true option, since the test is based on a sample of only 160 households, the entire population of households cannot be included.
Hence, the correct option is:
Option D. We are 95% confident that the mean amount spent on electric service among the 160 households is between $151 and $216.
Answer:
Income
Explanation:
Suppose the market wage for cashiers increases from $7 per hour to $9 per hour. As a result, Pat, who is a cashier, now works five more hours per week. On the other hand Chris, who is also a cashier, now works five fewer hours per week.Chris's behavior illustrates the <u>Income</u> effect of a wage increase.
As the income increases, few individual prefer to work fewer hours as now they are able to maintain target by working fewer than at previous wage rate. These people prefer leisure over higher income and want to settle down with limited income. These people may have a backward bending individual labour supply curve – they may choose to work fewer hours when the wage rate rises.
From the information, it can be inferred that it's an indication of the uncertainty that exists in the Vietnamese cultural model.
From the complete information, Vietnam has low points in the avoidance index. This implies that they're less associated with their cultural roots and don't have concern for hiring white people.
Some of the solutions that can be applied for training the workers include providing them with ethical and language-based training and also encourage a team culture.

Answer:
Unearned Fees ($3,600 × 6 months ÷ 12 months) $1,800
To Advertising revenue $1,800
(Being the adjusting entry is recorded)
Explanation:
The adjusting entry is shown below;
Unearned Fees ($3,600 × 6 months ÷ 12 months) $1,800
To Advertising revenue $1,800
(Being the adjusting entry is recorded)
Here we debited the unearned fees as it decreased the liability and credited the advertising revenue as it increased the revenue account
The six months could be computed from June 1 to December 31
Answer:
The optimal bundle is 6 pairs of dress shoes and 3 pairs of Crocs.
Explanation:
From the question,
Allowance (M) = $450; Price of dress shoes, Pd = $50; Price of crocs, Pc = $50
Note: MRS-price ratio, MUC- marginal utility from consuming casual Crocs ,MUD- marginal utility from consuming dress shoes
Optimal bundle is determined where MRS = Price ratio
MRS = MUC/MUD = 20DC/10C2 = 2D/C
Price ratio = Pd/Pc = 50/50 = 1
So, 2D/C = 1
Therefore, C = 2D
Budget constraint: M = Pd*D + Pc*C
So, 50D + 50*(2D) = 450
50D + 100D = 150D = 450
So, D = 450/150 = 3
C = 2D = 2*3 = 6
