An assistant to the mayor, who claims to understand statistics, complains about your confidence interval calculation. She assert

s that the dollar losses from burglaries are not normally distributed, which in turn makes the confidence interval calculations meaningless. Assume that she is correct about the distribution of money loss. Why are the calculations of a confidence interval still appropriate? According to the central limit theorem any distribution is considered normal if n is greater than ____. This sample is 500 so the distribution of the sample means will be normal, no matter what the shape of the actual distribution of dollar losses.

The central limit theorem indicates that as the size of a sample increases, the distribution of sample means approaches a normal distribution, irrespective of the population’s original shape. Typically, this is valid when the population size, denoted as n, is 30 or more (which means greater than 29). The population’s skewness or normality is not a factor in this scenario. Therefore, with a sufficiently large group, the mean results from sampling will equal the population mean.

What do you think policymakers expected would happen when they deregulated the trucking industry?
Scilla [3833]

Deregulation involves removing government oversight from a specific sector. If the trucking industry were deregulated, competition within it would intensify. Additionally, there would be fewer regulations ensuring that truckers abide by weight limits or refraining from transporting prohibited or illegal goods. Without regulation, guaranteeing timely delivery of products to stores would become more challenging.

Result:

The direct labor rate variance is positive $3,400.

Details:

Here’s the information we have:

The total actual labor cost for the company was $200,600, which covered 17,000 direct labor hours. The standard cost per hour is $12.

To find the direct labor rate variance, we begin by determining the actual rate.

Actual rate = $200,600 / 17,000 = $11.8 per hour.

Now we can compute the direct labor rate variance:

Direct labor rate variance = (Standard Rate - Actual Rate) * Actual Quantity

Direct labor rate variance = (12 - 11.8) * 17,000 = positive $3,400.

This variance is favorable as the actual rate was less than the standard rate.

arsen [3447]

Answer: 12750

According to the information provided, Jake’s Cabins is a modest motel chain located close to the national parks in Utah, Wyoming, and Montana, and the recorded data for guest nights in June is as follows:

4400, 3600, 2250, 2400, and 100.

To calculate the total guest nights for June, we will sum these amounts. This calculation results in:

= 4400 + 3600 + 2250 + 2400 + 100

= 12750

Thus, the total guest nights for June amount to 12750

stepan [3596]
Doc's ribhouse commenced with $52,000 in equity, generated $35,000 in net income, and distributed $12,000 in dividends. To find the ending equity, use the formula: Beginning Equity + Net Income - Dividends = Ending Equity. Plugging in the values gives us: $52,000 + $35,000 - $12,000 = Ending equity. This results in $52,000 + $23,000 = $75,000, confirming the ending equity is $75,000.
