Frank is lending $1,000 to Sarah for two years. Frank and Sarah agree that Frank should earn a real return of 4 percent per year
Montano1993 [528]

Answer:

nominal rate of interest is 31.7 %

Step-by-step explanation:

given data

payment = $1000

time = 2 year

rate = 4%

CPI = 100

CPI final yer = 127.7

to find out

nominal rate of interest

solution

we know nominal rate of interest formula that is

nominal rate of interest = real interest rate + inflation rate    .........1

so here inflation rate is express as

inflation rate = ( CPI final year - CPI )  / CPI  × 100    ...........2

put here value

inflation rate = ( 127.7 - 100 )  / 100  × 100

inflation rate is 27.7 %

so from equation 1

nominal rate of interest = real interest rate + inflation rate

nominal rate of interest = 4% + 27.7%

nominal rate of interest is 31.7 %

Statistical Tests? Indicate whether the following analysis involves a statistical test. If it does involve a statistical test, s
pashok25 [27]

Answer:

Yes, the given analysis involves a statistical test. Population parameter of interest = '% of community people living in mobile homes' (MH)

  • H0 : MH = 0.09
  • H1 : MH > 0.09

Step-by-step explanation:

Hypothesis testing is a statistical test, of testing an assumption (statement) about population parameter.

Null Hypothesis  [H0] is a neutral statement of 'no difference' about a population parameter; stating variable is no different than its mean.

Alternate hypothesis [H1] is the 'specific difference' stating hypothesis about a population parameter; contrary to the null hypothesis.

To determine if there is evidence for the claim that the percentage of people in the community living in a mobile home is greater than 9% :

This analysis can be done by using statistical test : one sided 't' test. The population parameter of interest would be '% of community people living in mobile homes' (MH)

  • H0 : MH = 9% → MH = 0.09
  • H1 : MH > 9% → MH > 0.09

GUYS, PLEASE ANSWER MY QUESTION! Please it's due today, everybody else got their questions answered! Listen to me!
Xelga [282]

Answer:

Arianna is correct

Step-by-step explanation:

She is correct because they need to find how much is the discounted price, which is 3. So to see what percentage it is, they need to see how much 3 is worth in comparison to 15. If we spilt 15 into 5 parts to make every part worth 20%, the answer would be 3. Thus Arianna is correct.
