Assume that the risk-free rate is 8 percent the required rate of return on the market is 13 percent and the required rate of ret

lapo4ka [179]

This is the formula for computing the required rate of return in a market: E(R) = Rf + ß( Rmarket - Rf ). This is called as the Capital Asset Pricing Model (CAPM). The E(R) represents the required rate of return; the Rf is the risk-free rate; the ß is the beta coefficient (which we are looking for); and the Rmarket is the rate of return on the market. Substituting the values to this formula, you can come up with the beta coefficient of 1.4.

A carpenter cuts a 5 feet 11 inch piece of board from a 10 feet 9 inch piece. What is the

Vikentia [17]

Answer:

4 feet and 9 inches

Step-by-step explanation:

first you want to take the 11 inches from the 9 but you can't so you would take the 3 missing inches from the 10 foot and that would make it 9 feet and 9 inches

then take 5 from the left over 9 and that is 4 so your answer would be 4 feet and 9 inches

The gas mileage for a certain model of car is known to have a standard deviation of 6 mi/gallon. A simple random sample of 36 ca

xxTIMURxx [149]

The 98% confidence interval for the mean gas mileage for this car model is (26.07,30.73).

Confidence intervals are defined as a range of values with a known chance that a parameter's value falls inside them.

The confidence interval of statistical data is computed using the formula:

$(\overline{x} - Z\frac{\sigma }{n},\overline{x} + Z\frac{\sigma }{n})$

where $\overline{x}$ is the mean, Z is the Z-score corresponding to the confidence interval, σ is the standard deviation, and n is the sample size.

In the question, the sample size (n) = 36, the mean of the sample ( $\overline{x}$ ) = 28.4 mi/gallon, the standard deviation (σ) = 6 mi/gallon.

The confidence interval given to us is 98%.

Z-score corresponding to this (Z) = 2.33.

Thus, the confidence interval can be calculated as:

(28.4 - 2.33{6/√36},28.4 + 2.33{6/√36})

= (28.4 - 2.33,28.4 + 2.33)

= (26.07,30.73).

Thus, the 98% confidence interval for the mean gas mileage for this car model is (26.07,30.73).
