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

If a security currently worth $12,800 will be worth $15,573.16 five years in the future, what is the implied interest rate the i
Anna007 [38]

The implied rate of interest is 4.00%

Explanation:

Principal (initial security worth)- $ 12,800

Final amount - $ 15,573.16

Time taken – 5 years

No additional deposition or withdrawal in between

∴ Rate of interest

This is the problem pertaining to compounding interest.

We know that for compound interest

Amount (A)= Principal(P)(1+R/100)ⁿ

Where R= rate of interest

N= time period

Thus, equation can be rearranged as  

A/P=(1+R/100)ⁿ

Substituting the values of A, P and n as $15,573.16, $12800 and 5 years respectively

15573.16/12800=(1+R/100)⁵

Solving the above equation we would get R as 4%

Exercise 8-3
7nadin3 [17]

Answer:

(a) Prepare the entries to record sales and collections during the period.

  • It had net credit sales of $800,000  

Dr Accounts receivable $ 800,000

Cr Sales $ 800,000

  • Collections of $763,000.

Dr CASH $ 763,000

Cr Accounts receivable $ 763,000

(b) Prepare the entry to record the write-off of uncollectible accounts during the period.

  • It wrote off as uncollectible accounts receivable of $7,300  

Dr Allowance for Uncollectible Accounts $ 7,300

Cr Accounts receivable $ 7,300

(c) Prepare the entries to record the recovery of the uncollectible account during the period.

  • However, a $3,100 account previously written off as uncollectible was recovered before the end of the current period.  

Dr Accounts receivable $ 3,100

Cr Allowance for Uncollectible Accounts $ 3,100

(d) Prepare the entry to record bad debt expense for the period.

  • Uncollectible accounts are estimated to total $25,000 at the end of the period.  

Dr Bad Debt Expense $ 20,200

Cr Allowance for Uncollectible Accounts $ 20,200

Explanation:

If the company applies the allowance method, it means that the account Allowance for Uncollectible Accounts must show as balance the estimated value of $25,000

Because the company already has a CREDIT balance in the Allowance for Doubtful Accounts it's necessary to register an entry that complement the existing value and reflect the estimated value, $ 20,200  

Bad accounts are those credits granted by the company and there is no possibility of being charged.

When customers buy products on credits but the company cannot collect the debt, then it's necessary to cancel the unpaid invoice as uncollectible.

One way is to directly cancel bad debts at the time it was decided that the credit is bad, the total amount reported as bad debt expenses negatively affect the income statement and the accounts receivable are reduced by the same amount, less assets

The other way is to determine a percentage of the total amount of accounts receivable as bad debts, there are many ways to analyze accounts receivable and calculate the value of bad debts.

When the company has the percentage of uncollectible accounts, the required journal entry is Bad Expenses (debit) with Reserve for Bad Accounts (credit)

At the time of cancellation, since the expenses were recognized before, we only use the Allowance for Uncollectible Accounts (Debit)  with accounts receivable (credit), with this we are recognizing the bad credit of the company.
