A bilateral contract is one in which one side promises to perform in exchange for the other side's actions

ss7ja [257]

The statement is false.

Void and voidable contracts are one and the same. Exculpatory clauses are typically considered void towards public coverage. Covenants not to compete are commonly taken into consideration void as against public coverage.

A bilateral contract is a contract in which each party alternate guarantees to carry out. One birthday party's promise serves as consideration for the promise of the other. As a result, each party is an obligor of that birthday celebration's own promise and an obligee of the opposite's promise.

A contract wherein the events trade a promise for a promise is referred to as a Bilateral contract, whereas a contract wherein one birthday party gives a promise and the other birthday celebration performs an act is known as a Unilateral settlement. these legally enforceable promises can be in writing or oral.

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)

eimsori [14]

Answer:

c. The statement is false because the demand for incandescent light bulbs would increase as the price of compact fluor. light bulbs fell.

Explanation:

If improvements in production technology reduce the price of incadescent light bulbs, the normal thing that would happen is that demand for this good would increase, because now people will be able to buy the good at a lower price.

Vika [28.1K]

The complete question is as follows:

The admission directory of Big City University has a novel idea. He proposed using the IQ scores of current students as a marketing tool. The university agrees to provide him with enough money to administer IQ tests to 50 students. So the director gives the IQ test to an SRS of 50 of the university’s 5000 freshman. The mean IQ score for the sample is xbar=112. The IQ test he administered is known to have a σ of 15. What is the 95% Confidence Interval about the mean? What can the director say about the mean score of the population of all 5000 freshman?

Answer: The 95% confidence interval about the mean is $Confidence interval = 107.84 \leq \mu \leq 116.16$ .

The director can say that he is 95% confident that the mean IQ score of the 5000 freshmen lies between 107.84 and 116.16.

We follow these steps to arrive at the answer:

Since the population standard deviation of the IQ test is known, we can use the Z scores to find the confidence interval.

The formula for the confidence interval about the mean is:

$Confidence interval = \overline{X}\pm Z*\frac{\sigma}{\sqrt{n}}$

In the equation above, X bar is known as the point estimate and the second term is known as Margin of Error.

The Critical Value of Z at the 95% confidence level is 1.96.

Substituting the values in the question in the equation above we have,

$Confidence interval = \112\pm 1.96*\frac{15}{\sqrt{50}}$

$Confidence interval = \112\pm 4.157787873}$

$Confidence interval = 107.8422121 \leq \mu \leq 116.1577879$
