If P(A or B) = 0.8, P(A) = 0.3, and P(A and B)= 0.15, find P(B).

Dennis_Churaev [7]

Answer:

P(B) = 0.65

Step-by-step explanation:

The appropriate formula is ...

P(A or B) = P(A) +P(B) -P(A and B)

Then P(B) is ...

P(B) = P(A or B) +P(A and B) -P(A)

P(B) = 0.8 +0.15 -0.3

P(B) = 0.65

What would you pay for a $215,000 debenture bond that matures in 15 years and pays $10,750 a year in interest if you wanted to e

velikii [3]

Answer:

at 4% $238,904.53

at 5% $215,000

at 6% $194,118.66

Step-by-step explanation:

Yield is the return received on the investment, The rate of yield is determined by calculating the percentage of return to total investment.

Price of the bond is the present value of all cash flows of the bond. These cash flows include the coupon payment and the maturity payment of the bond.

According to given data

Face value of the bond is $215,000

Coupon payment = C = $10750 annually

Number of periods = n = 15 years

Price of the bond is calculated by following formula:

Price of the Bond = C x [ ( 1 - ( 1 + r )^-n ) / r ] + [ F / ( 1 + r )^n ]

Yield = 4% annually

Price of the Bond = 10,750 x [ ( 1 - ( 1 + 4% )^-15 ) / 4% ] + [ $215,000 / ( 1 + 4% )^15 ] = $238,904.53

Yield = 5% annually

Price of the Bond = 10,750 x [ ( 1 - ( 1 + 5% )^-15 ) / 5% ] + [ $215,000 / ( 1 + 5% )^15 ] = $215,000

Yield = 6% annually

Price of the Bond = 10,750 x [ ( 1 - ( 1 + 6% )^-15 ) / 6% ] + [ $215,000 / ( 1 + 6% )^15 ] = $194,118.66

In Test A, suppose you make 100 experimental measurements of some quantity and then calculate mean, standard deviation, and stan

Scrat [10]

Answer:

D.) I would expect the means and standard deviations in the two test to be about the same, but the standard error in Test B should be smaller than in Test A.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean $\mu = p$ and standard deviation $s = \sqrt{\frac{p(1-p)}{n}}$

By the Central Limit Theorem:

Both tests, A and B, are of the same quantity, so they have the same mean and standard deviation. However, since the standard error is inversely proportional to the sample size, and test B has a greater sample size than test A, the standard error in test B should be lower, and thus, the correct answer is given by option D.
