If the sampling distribution of the sample proportion is normally distributed with n=20, then calculate the probability that the sample proportion is between 0.10 and 0.12. (Round final answer to 4 decimal places.)
We cannot assume that the sampling distribution of the sample mean is normally distributed. We can assume that the sampling distribution of the sample mean is normally distributed and the probability that the sample mean is less than 12.5 is Probability
Answers
To calculate the probability that the sample proportion is between 0.10 and 0.12, we need to standardize the sample proportion using the formula:
z = (p - P) / sqrt(P * (1 - P) / n)
p is the sample proportion
P is the population proportion (assumed to be unknown)
n is the sample size
Using this formula, we get:
z1 = (0.10 - 0.5) / sqrt(0.5 * (1 - 0.5) / 20) = -2.83
z2 = (0.12 - 0.5) / sqrt(0.5 * (1 - 0.5) / 20) = -2.12
To find the probability that the sample proportion is between 0.10 and 0.12, we need to find the area under the standard normal distribution curve between z1 and z2. We can use a standard normal distribution table or a calculator to find this probability. For example, using a calculator with a standard normal distribution function, we get:
P(-2.83 < z < -2.12) = 0.0216
Therefore, the probability that the sample proportion is between 0.10 and 0.12 is 0.0216, rounded to 4 decimal places.
Regarding the second part of the question, we cannot answer it because the information provided is incomplete. We need to know the mean and standard deviation of the population, as well as the sample size and level of significance, to determine the probability that the sample mean is less than 12.5.

To find the probability that the sample mean is less than 12.5, we need to first estimate the population mean and standard deviation. If we do not have this information, we cannot calculate the probability.
To calculate the probability that the sample proportion is between 0.10 and 0.12, we can use the formula for the standard error of the sample proportion:
SEp = sqrt[p(1-p)/n]
where p is the population proportion (unknown) and n is the sample size (given as 20). Since we do not know the population proportion, we can use the sample proportion (p-hat) as an estimate:
p-hat = (number of successes in sample)/n
We can then use the z-score formula to standardize the sample proportion:
z = (p-hat - p)/SEp
Since the sampling distribution of the sample proportion is normally distributed, we can use a standard normal distribution table to find the probability that the sample proportion is between 0.10 and 0.12. We first calculate the z-scores for each end of the interval:
\(z1 = (0.10 - p-hat)/SEp\\z2 = (0.12 - p-hat)/SEp\)
Using a standard normal distribution table, we find the area under the curve between these two z-scores, which represents the probability that the sample proportion is between 0.10 and 0.12. The final answer is rounded to 4 decimal places.
Regarding the second part of the question, we can assume that the sampling distribution of the sample mean is normally distributed if either the sample size is large (n > 30) or the population distribution is normal. If we can assume normality, we can use the z-score formula to standardize the sample mean:
\(z = (x-bar - mu)/(sigma/sqrt(n))\)
where x-bar is the sample mean, mu is the population mean (unknown), sigma is the population standard deviation (unknown), and n is the sample size (unknown).
To find the probability that the sample mean is less than 12.5, we need to first estimate the population mean and standard deviation. If we do not have this information, we cannot calculate the probability.

Cain Company reports net cash provided by operating activities of $35,000. It also reports the following information under “Adjustments to reconcile net income to net cash provided by operating activities” on its statement of cash flows (using the indirect method).
Answers
It can be seen from the solutions given that Cain's net income is $24,000.
Here is the solution:Net income = Net cash provided by operating activities - Adjustments
= $35,000 - $6,000 - $10,000 + $4,000 + $7,000 + $4,000
= $24,000
Therefore, Cain's net income is $24,000.
Here is a breakdown of the adjustments:
To determine cash flow from operations, it is necessary to include the gain on equipment sales in the net income as it is a non-cash entry.
A rise in accounts receivable implies that customers are prolonging payment of their invoices, resulting in decreased cash flow from the company's activities.
The depreciation expense is classified as a non-cash expense, hence it must be included in the calculation of cash from operations by adding it back to the net income.
A decrease in inventory indicates that the company is experiencing faster turnover of its inventory, leading to increased cash flow generated by its operations.
A rise in prepaid expenses denotes that the company is channeling more funds towards prepaid expenditures like insurance and rent, implying a reduced cash inflow from its operational activities.
A decline in the amount of wages that the company owes indicates that it is not promptly compensating its workforce. Consequently, this implies that the company's operational cash flow is reduced.

(Check all that apply and then click 'Submit?) The ammonium nitrate could have been mixed with fuel oil to lower the potential for an explosion. The ammonium nitrate storage bin could have been made wider but shorter so that the same amount was stored. Less ammonium nitrate could have been stored at the facility. The facility could have been constructed to store twice as much ammonium nitrate. Larger amounts decrease the potential for ammonium nitrate to detonate.
Answers
The changes that could have made the explosion less destructive are:
The ammonium nitrate could have been mixed with fuel oil to lower the potential for an explosion.Less ammonium nitrate could have been stored at the facility.Options A and C are the correct answers.
Mixing ammonium nitrate with fuel oil creates a mixture called ANFO (Ammonium Nitrate Fuel Oil), which is less sensitive to detonation compared to pure ammonium nitrate. This would have reduced the risk of a catastrophic explosion. Additionally, storing less ammonium nitrate at the facility would have reduced the overall quantity of explosive material present, thereby decreasing the potential for a destructive explosion.

What annual nominal rate compounded monthy has the same annual percentage yieid as 10% compounded continuously? The annual nominal rate is ______%. (Round to two decimal places as needed.)
Answers
The annual nominal rate compounded monthly is 12%.
The annual percentage yield is 10%, compounded continuously. We need to find the annual nominal rate compounded monthly. Let P = $100, r be the annual nominal rate compounded monthly, n = 12 be the number of compounding periods per year, and t = 1 be the time in years.
Using the formula, A = P(1 + r/n)nt
When the annual percentage yield is 10% compounded continuously, then we have:
A = Pert
Where A = 100(1 + 10%) = $110.00
P = 100r = P/e(yt)
= 100/e(0.10 × 1)
= 100/e0.10
= $90.48
By comparing A = Pert and A = P(1 + r/n)nt, we get:
110 = 100(1 + r/12)12r
Solve for r:
110/100 = (1 + r/12)12r1.1 = (1 + r/12)12r
Take the natural logarithm of both sides:
ln(1.1) = 12r ln(1 + r/12)
Using the fact that ln(1 + x) ≈ x when x is small: ln(1.1) ≈ 0.1 = 12r (r/12)0.1 = r/12r = 0.12 or 12%
