Answer:

The 99% confidence interval would be given by (12004.26;12995.74)

Explanation:

1) Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

$\bar X=12500$ represent the sample mean for the sample

$\mu$ population mean (variable of interest)

s=700 represent the sample standard deviation

n=17 represent the sample size

2) Confidence interval

The confidence interval for the mean is given by the following formula:

$\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}$ (1)

In order to calculate the critical value $t_{\alpha/2}$ we need to find first the degrees of freedom, given by:

$df=n-1=17-1=16$

Since the Confidence is 0.99 or 99%, the value of $\alpha=0.01$ and $\alpha/2 =0.005$ , and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-T.INV(0.005,16)".And we see that $t_{\alpha/2}=2.92$

Now we have everything in order to replace into formula (1):

$12500-2.92\frac{700}{\sqrt{17}}=12004.26$

$12500+2.92\frac{700}{\sqrt{17}}=12995.74$

So on this case the 99% confidence interval would be given by (12004.26;12995.74)

Hardin Company received $120,000 in cash and a used computer with a fair value of $360,000 from Page Corporation for Hardin Comp

san4es73 [151]

Answer:

$30,000 and $360,000

Explanation:

The computation of the gain on the exchange is shown below:

= Cash received + fair value of the computer - undepreciated cost of existing computer

= $120,000 + $360,000 - $450,000

= $30,000

The amount of the computer which is recorded will equal to the fair value of the computer i.e $360,000

For computing the gain we simply added the fair value and deduct the undepreciated cost of an existing computer in the cash received amount so that the accurate amount can come.

All other information which is given is not relevant. Hence, ignored it
