Answer:

H0 : β = 0

H1 : β = 0

R = 0.8642

P value = 0.002654

Explanation:

Null hypothesis : H0 : β = 0

Alternative hypothesis : H1 : β ≠ 0

The correlation Coefficient, R value as obtained using a correlation Coefficient calculator is 0.8642. This depicts that a strong positive relationship exists between court income and Justice salary.

The Pvalue using the Pvalue calculator (R = 0.8642, N = 9) = 0.002654

The Pvalue < α

0.002654< 0.05 ; Hence, we reject H0.

What sum of money today is equivalent to $8,250 2 years from now, if annual interest rate is 4%, compounding semi-annually?
Mariulka [41]

Answer:

$7,621.72

Explanation:

The equation that describes the future value (FV) of an investment (P) at an interest rate (r) for a period of n years, compounded semi-annually is:

FV = P*(1+\frac{r}{2})^{2n}

The amount required to yield $8,250 after 2 years at a rate of 4% per year is:

8,250 = P*(1+\frac{0.04}{2})^{2*2} \\P=\$7,621.72

Allowance for doubtful debts = Sales * Percentage for doubtful debts

Allowance for doubtful debts = $500,000 * 1% = $5,000

Now always remember that this amount will be used only and their is no need to include the allowance for doubtful accounts balance.

Dr Bad Debt Expense $5000

Cr Allowance for Doubtful Debts $5000
