An urban economist wishes to estimate the mean amount of time people spend travelling to work. He obtains a random sample of 60

individuals who are in the labour force and finds that the mean travel time is 30.5 minutes. Assuming that the population standard deviation of travel time is 20.5 minutes, construct and interpret a 90% confidence interval for the mean travel time to work. (Note: the standard deviation is large, because some people work at home and thus travel 0 minutes and some people take transit which results in large travel times).

Answer:

An urban economist wishes to estimate the mean amount of time people spend traveling to work. He obtains a random sample of 50 individuals who are in the labor force and finds that the mean travel time is 24.2 minutes. Assuming the population standard deviation of travel time is 18.5 minutes, construct and interpret a 95% confidence interval for the mean travel time to work. Note: The standard deviation is large because many people work at home (travel time =0 minutes) and many have commutes in excess of 1 hour. (Source: Based on data obtained from the American Community Survey.)

azamat

Answer:

The price of the bonds is $ 1,276.

Explanation:

The value of bond or issue price can be calculated by discounting all future cash flow using effective rate of retun. Detail calculations are given below.

Future Value = Redemption present value (RPV) + Present value of interest   (PVI)

RPV = 1,000 (1+5%)^-15 = $ 481 -A

PVI = 36.25 * Annuity factor  =$ 759 -B

Future Value = A + B = $ 1,276  

Annuity factor = (1- (1+i%)^-n)/i% = (1- (1+5%/2)^-30)/(5%/2) = 20.9303

solong [7]

Answer:

The capital deficiency of $33,000 will be shared between Turner and Roth in the proportion of their income and loss sharing ratio of 2:3.

Turner will need to further contribute $13,200 ($33,000 x 2/5)

Roth will contribute $19,800 ($33,000 x 3/5)

Lowe is a limited partner and will not contribute to the capital deficiency.

Explanation:

Lowe as a limited partner is a part-owner of the partnership but his liability for the firm's debts cannot exceed $32,000 being the amount that has invested in the company.  As a silent partner, Lowe does not participate in the management of the company.

The Limited Partnership of Turner, Roth, and Lowe is a partnership consisting of general partner(s) like Turner and Roth, who manage the business and have unlimited personal liabilities for the debts and obligations of the Limited Partnership and Lowe as the limited partner.  Whereas, Turner and Roth are in charge of the management of the company, Lowe is a silent partner.
