Answer:

14.34%

Explanation:

To find the percentage of returned surveys over the total we divide and then multiply:

(717/5000)*100= 14.34%

The response rate appears to be low because it is less than 50% (which would be 2500 return surveys). Some statistical studies agree that 30 is the minimum number of observations a study must have, but this number does not ensure statistically significant results.  

The problem with a very low response rate is that survey´s answers does not significant represent the study population characteristics and so we cannot make inferences, correlations or regressions that are statistically significant. In this case, the conclusions that scientists make about association between the left-handed population and right-handed population with the use of cell phone calls could be wrong or not represent the population characteristics, which means answers are not trustful.

Margaret [11]

Answer:

36.26%

Explanation:

Simple rate of return:

return/investment

<u>return:</u>

In this case, it will be the cost saving for the new machine: 161,000

<u>investment</u>

We will decrease the investment by the recovery from the old machine.

468,000 new machine - 24,000 salvage value of new   = 444,000

<u>Then, proceed to calculate:</u>

161,000/444,000 = 0.3612 = 36.26%

Consideration:

Is important to state that this rate, do not consider the time value of money, neither the cash flow of the project.

If a taxpayer does not have enough taxes withdrawn from her paychecks throughout the year to equal the total tax she is required
polet [3.4K]

Answer:

$209

Explanation:

Since Mary's estimated annual income taxes are $5,424, then to determine the amount that should be withheld every two weeks, all we need to do is divide her total estimated taxes by 26 weeks = $5,424 / 26 weeks = $208.62 ≈ $209. generally you do not include cents in tax filings or payments, you need to round up or down. In this case you need to round up, even software rounds the amounts to the nearest dollar.
