Answer:

Null hypothesis: The average life expectancy of tires produced by the Whitney Tire Company is 40,000 miles.

Alternate hypothesis: The average life expectancy of tires produced by the Whitney Tire Company is greater than 40,000 miles.

Explanation:

A null hypothesis is a statement from a population parameter which is either rejected or accepted (fail to reject) upon testing. It is expressed using the equality sign.

An alternate hypothesis is also a statement from the population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected. It is expressed using any of the inequality signs.

Answer:

Yield to call is 9.8%

Explanation:

The rate of return bonholders receives on a callable bond until the call date is called Yield to call.

Yield to Call = [ C + ( F - P ) / n ] / [ (F + P ) / 2 ]

C = Coupon Payment = $105 per year

F = Face value = $1,000

P = Call price = $1,100

n -= number of years to call = 5

Yield to Call = [ $105 + ( $1,000 - $1,100 ) / 5 ] / [ ( $1,000 + $1,100 ) / 2 ]

Yield to Call = [ $105 - 2 ] / $1,050 = $103 / $1,050 = 0.098 = 9.8%

Assume that the money demand function is (M/P)d = 2,200 – 200r, where r is the interest rate in percent. The money supply M is 2
liubo4ka [24]

Answer: The nominal money supply should set at 1,600.

Explanation:

Given that,

Money demand function: (M/P)d = 2,200 – 200r

r - Interest rate

Money supply (M) = 2,000

Price level (P) = 2

If the fed wants to set the interest rate at 7% then,

Money supply = money demand

(\frac{M}{P})^{s} = (\frac{M}{P})^{d}

\frac{M}{P} = 2,200 – 200r

P = 2 and r = 7%

\frac{M}{2} = 2,200 – 200 × 7

                            M = 800 × 2

                            M = 1,600

The nominal money supply should set at 1,600.
