In recent years the mean number of miles driven per year by residents of a particular state was 11,568. A researcher wishes to t

est, at the 5% level of significance, whether the mean is different now. In a random sample of 62 drivers, the mean and sample standard deviation of the number of miles driven last year were 10,822 and 1,741, respectively. The rejection region for the relevant test is:

Answer:

The degrees of freedom are given by:

df =n-1= 62 -1=61

And we want to find a critical value on the t distribution with 61 degrees of freedom who accumulates 0.025 of the area on each tail and the critical value would be t_{\alpha/2}= \pm 2.00

And the rejection region would be |t_{calc}| >2.00

Step-by-step explanation:

Data given and notation  

\bar X=10822 represent the sample mean  

s=1741 represent the sample standard deviation

n=62 sample size  

\mu_o =11568 represent the value that we want to test  

\alpha=0.05 represent the significance level for the hypothesis test.  

z would represent the statistic (variable of interest)  

p_v represent the p value for the test (variable of interest)  

State the null and alternative hypotheses.  

We need to conduct a hypothesis in order to check if the true mean differs from 11568, the system of hypothesis would be:  

Null hypothesis:\mu =11568  

Alternative hypothesis:\mu \neq 11568  

The degrees of freedom are given by:

df =n-1= 62 -1=61

And we want to find a critical value on the t distribution with 61 degrees of freedom who accumulates 0.025 of the area on each tail and the critical value would be t_{\alpha/2}= \pm 2.00

And the rejection region would be |t_{calc}| >2.00

Find the next number in the number sequence 1,2,4,8,16,...<br> A) 24<br> B) 12<br> C) 20<br> D) 32
Fantom [35]

Answer:

D.

Step-by-step explanation:

To get from 1 to 2 you multiply by 2.

To get from 2 to 4  you multiply by 2.

Notice how each number is multiplied by 2? Now try multiplying 16 times 2 which would be 32.

On the first day of the fiscal year, Shiller Company borrowed $85,000 by giving a seven-year, 7% installment note to Soros Bank.
Lera25 [3.4K]

Answer

A₁ - Journal entry at the time of issue of installment note for cash:

Bank A/c                              Dr           $85,000

To Notes Payable               Cr           $85,000

A₂– Journal entry at the time of first annual payment:

Notes Payable A/c           Dr           $9,822

Interest Expense A/c       Dr           $5,950

To Bank A/c                   Cr                            $15,772

Notes payable to be reported in balance sheet at the end of fiscal year:

Notes payable end balance = $85,000 - $9,822 = $75,178

Interest for 2nd year = $75,178 * 7% = $5,262

Installment amount for 2nd year = $15,772  

Principal repayment for 2nd year = $15,772 - $5,262 = $10,510

Therefore out of $75,178 notes payable, $10,510 is payable within 1 year.

There $10510 will be shown in balance sheet as current liabilities and

remaining $64,668 will be shown in balance sheet as long term liability.
