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.)

bonufazy [111]

According to the scenario, the given data are as follows:

Initial price = $117

Ending price = $147

Dividend = $3.10

(a) We can calculate the Total return percentage by using following formula:

Total return percentage = ( Ending Price - Initial Price + Dividend) ÷ Initial Price

By putting the value, we get

Total return percentage = ( $147 - $117 + $3.10) ÷ ( $117)

What is the ending balance on the statement of changes in owner's equity for this data?
creativ13 [48]

The Owner's Equity statement illustrates the capital account changes due to contributions, withdrawals, net income, or a net loss. So Ending Balance of the statement of changes in Owner's equity will be; Opening capital + Capital Added + Net Income - Owner's Withdrawals.

A one-page report titled a "statement of owner's equity" compares all assets and liabilities to determine the owner's equity's overall value. The snapshot, which is tracked over a predetermined time period or accounting period, depicts the flow of cash through a company.

Owner's equity is simply the difference between the owner's initial investment in the business and any withdrawals made by the owner. For instance: A real estate project with a value of $500,000 and a loan balance of $400,000 would have $100,000 in owner's equity.
