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.

An investor is in a 30% combined federal plus state tax bracket. If corporate bonds offer 9% yields, what yield must municipals
Yuki888 [10]

Answer:

0.063 or 6.3% (or more)

Explanation:

Given:

Combined Tax Bracket = 30% = 30/100 = 0.30

Yields of corporate Bonds = 9% = 9/100 = 0.09

Yield to Shift Investors to choose municipal bonds = ?

Calculation:

Yield from corporate bond = (After tax yield) x Yield rate of corporate Bonds

                                              = (0.70) x (0.09)

                                              = 0.063 or 6.3%

Working note:

After tax yield = (1 - tax rate )

After tax yield = (1 - 0.30 )

After tax yield = (0.70)

so, they must give 6.3% yield
