Suppose you are interested in studying whether scent affects spatial reasoning abilities. You decide to test spatial reasoning u

sing completion time scores for the paper-folding test with five people, repeating the test on each person with three different scents (cinnamon, lavender, and peppermint). In this experiment, the null hypothesis is that:
a. The completion time mean for at least one scent is different from another
b. There are no individual differences in the completion time means
c. There are no differences in the mean completion times among the scents compared
The factor of interest is the ___. and the dependent variable is the ___.

Answer: 1. c. There are no differences in the mean completion times among the scents compared

2. Scent; Completion Time

Explanation:

The Null Hypothesis of a research is that hypothesis which you aim to disprove because it holds that no significant relationship between the variables being researched exists.

In this scenario you are studying whether scent affects spatial reasoning abilities.

The Null Hypothesis will.be that which states that there is no relationship between scent and spartial reasoning therefore there will be no differences in the mean completion times among the scents compared.

The factor of interest is the variable that is being changed to examine a difference making it the SCENT in this scenario.

The dependent variable changes due to the Factor of Interest so it is the COMPLETION TIME.

TEA [102]

Answer:

Option d. $30,028,394.34

Explanation:

We can calculate certainty equivalent NPV by just a simple formula

Certainly equivalent NPV = Certain cashflow/(1+r)^n

Certain cashflows =Net cashflows x Certainty equivalent factor

r = risk free rate

At first, we need to find certain cash flows

Certain cash flow

Year1: $15,000,000  x 0.90  = $13,500,000

Year2: $13,000,000  x 0.80 = $10,400,000

Year 3: $11,000,000 x  0.60  = $6,600,000

Year 4: $9,000,000 x 0.35  =$3,150,000.

Certainly Equivalent NPV = [$13,500,000 / (1+0.06)^1] + [$10,400,000 / (1+0.06)^2] + [$6,600,000 / (1+0.06)^3] + [$3,150,000 / (1+0.06)^4]

Certainly Equivalent NPV = $12,735,849.06 + $9,255,962.98 + $5,541,487.27 + $2,495,095.04 = $30,028,394.34

Combining two assets having perfectly positively correlated returns will result in the creation of a portfolio with an overall r
lisabon 2012 [21]

Answer:

The correct option is (B)

Explanation:

The main objective of creating a portfolio is to minimise the overall risk of investments. Two investments with the same correlation signs are riskier because, if one investment gives a negative return, the other investment will do the same. The combined loss is more than the loss one investment will sustain. The portfolio is always constructed by adding investments with opposite correlation signs.
