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.

Suppose a​ seven-year, $ 1 comma 000 bond with a 7.8 % coupon rate and semiannual coupons is trading with a yield to maturity of
n200080 [17]

Answer:

The price of the bond is  1,072.19  

Explanation:

The price at which the bond trades for can be computed using the pv formula in excel which tries to discount to present value all the cash inflows receivable from the bond into today's present worth.

=-pv(rate,nper,pmt,fv)

rate is the yield to maturity of 6.50% divided by 2 since the bond pays interest semi-annually i.e 3.25%

nper is the number of coupon payments the bond would pay which is 7 years multiplied by 2 i.e 14

pmt is the semi-annual interest of the bond which is $1000*7.8%/2=$39

the fv is the face value of the bond of $1000

=-pv(6.5%/2,14,39,1000)=$1,072.19

kirza4 [7]

Answer: B. Bought the bonds from Dalrymple and sold them to the public

Explanation:

Investment Banks help companies issuing new securities in diverse ways to ensure that they raise the capital they are looking for. Some of the ways they help include; underwriting securities and market research. The main way they help companies issuing new securities however, is underwriting.

With Underwriting, the Investment Bank usually buys all the securities on offer from the Issuing company, then sells them at higher price to make a profit. This helps the issuing company because they get to sell all or most of their securities so it reduces uncertainty.

The Commonwealth Bank of Australia therefore bought the bonds from Dalrymple and sold them to the public.

guapka [62]

Answer:

Cost of Goods Sold = $234,000

Option B is correct ($234,000)

Explanation:

First we will calculate total direct material used in production:

Total Direct material=Starting Direct Material+ Purchases of Direct Material+ Ending Direct material

Total Direct material=$40,000+$75,000-$43,000

Total Direct material=$72,000

Calculating Cost of goods Manufactured:

Cost of goods Manufactured=Total Direct material+Direct labor+ Manufacturing Overhead+Beginning WIP inventory-Ending WIP inventory

Cost of goods Manufactured=$72,000+$48,500+$72,500+$87,000-$69,000

Cost of goods Manufactured=$211,000

Cost of Goods Sold = Cost of goods Manufactured+ Starting Finished Goods-Ending Finished Goods

Cost of Goods Sold = $211,000+$128,000-$105,000

Cost of Goods Sold = $234,000

Option B is correct ($234,000)
