Answer:

a. H0 : U ≥ 15

   Ha : U < 15

b. Type I error is incorrectly conclude that the pain is reduced in less than 15 minutes.

c. Type II error is fail to conclude that time for pain reduction is less than 15 mints when actually its less than 15 minutes.

Explanation:

Null hypothesis is a statement that is to be tested against the alternative hypothesis and then decision is taken whether to accept or reject the null hypothesis.

Type I error is one in which we reject a true null hypothesis.

Type II error is one in which we fail to reject the null hypothesis that is actually false.

Lindsay needs to purchase a car. The car Lindsay is planning on
Alika [10]

The quantity a lender costs a borrower and is a percent of the principal of the quantity loaned; is called as an interest rate. The total amount of interest she will pay is $418.68

<h3>What do you mean by interest on a loan?</h3>

A mortgage is normally mentioned on an annual foundation referred to as the once-a-year percent fee (APR). It is known as interest rate.

As per the information,

Costs = $10,000, Down payment is equal to $1,000; where PV is the amount owing = $9,000

Rate of interest is 3%, that is 3%/12 =  0.0025;

n is the number of periods = 3 x 12 = 36 months.

A) The dollar amount that Lindsay will need to finance is $9,000

B) Now, to calculate the installment amount to be paid that is P:

PV = P(\frac{1 - (1 + r)^{-n} }{r} )\\\

9,000 = P(\frac{1 - (1 + 0.0025)^{-36} }{0.0025} )\\\\\\9,000 = P\frac{ ( 1 - 0.9140)}{0.0025} \\\\9,000 = 34.4P\\\\P = $261.63\\\\Hence, the amount of installment that she will pay = \$261.63

C)The actual cost of the car after financing = $1,000 + $261.63 x 36 = $10418.68

The total amount of interest she will pay = $10418.68 - $10,000 = $418.68

<em>D. Greenfield investments: </em>The company will establishes operations on the country. It will have a high cost, but will get the goverment approval for the jobs created in China. However it will be Axiom who takes the cost and risk for the entire investment.
