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.

Seventy new jobs are opening up at an automobile manufacturing plant, and 1000 applicants show up for the 70 positions. To selec
777dan777 [17]

Answer:

  • <em>As explained below, given that the score of the person is among the 0.03125 fraction of the best applicants, </em><u><em>he can count on getting one of the jobs.</em></u>

<em></em>

Explanation:

The hint is to use <em>Chebyshev’s Theorem.</em>

Chebyshev’s Theorem applies to any data set, even if it is not bell-shaped.

Chebyshev’s Theorem states that at least 1−1/k² of the data lie within k standard deviations of the mean.

For this sample you have:

  • mean: 60
  • standard deviation: 6
  • score: 84

The number of standard deviations that 84 is from the mean is:

  • k = (score - mean) / standar deviation
  • k = (84 - 60) / 6 = 24 / 6 = 4

Thus, the score of the person is 4 standard deviations above the mean.

How good is that?

Chebyshev’s Theorem states that at least 1−1/k² of the data lie within k standard deviations of the mean. For k = 4, that is:

  • 1 - 1/4² = 1 - 1/16 = 0.9375

  • That means that half of 1 - 0.9375 are above k = 4: 0.03125

  • Then, 1 - 0.03125 are below k = 4: 0.96875

Since there are 70 positions and 1,000 aplicants, 70/1,000 = 0.07. The compnay should select the best 0.07 of the applicants.

Given that the score of the person is among the 0.03125 upper fraction of the applicants, this person can count of geting one of the jobs.

VLD [36.1K]

Answer: $16.69

Explanation:

Using the Dividend growth model, the value is:

= [Dividend 1/ (1 + required return)] + [Dividend 2/ (1 + required return)²] + [Terminal value / (1 + required return)²]

Terminal value = Dividend after 2 years / (required return - growth)

= 2.50/ (14.5% + 0%)

= $17.24

Dividend 1 = 3.60 * ( 1 -30%)                                Dividend 2 = 2.52 * ( 1 -30%)

= $2.52                                                                                     = $1.76

Market value = (2.52 / 1.145) + (1.76 / 1.145²) + (17.24/1.145²)

= $16.69

If the United States wanted to reduce the cost of its goods in foreign markets, it could ________ its currency.
Kruka [31]

Answer:

Devalue its currency

Explanation:

Exchange Rate is the conversion rate of domestic & foreign currency.

Eg $1 =   _ € .

Devaluation means deliberate fall in value of domestic currency in terms of foreign currency (increase in foreign exchange rate) , under fixed exchange rate by government.

Eg :  $1 =   5€ - change to -  $1 = 7€ . This implies dollar can purchase less amount of euro , and has depreciated.

However , this would also lead to reduce the cost of its exports in foreign (here European market) , because US $ has become cheaper in terms of their currency & hence so have been their goods.
