a study of an association between which ear is used for cell phone calls and whether the subject is left - handed or right - handed began with a survey e - mailed to 5000 people belonging to an otology online group, and 717 surveys were returned. (otology relates to the ear and hearing.) what percentage of the 5000 surveys were returned? does that response rate appear to be low? in general, what is a problem with a very low response rate? of the 5000 surveys, % were returned. this response rate to be low. (round to the nearest whole number as needed.)
Answer
# Explanation:
## Step1: Recall percentage formula
The formula for percentage is $\text{Percentage}=\frac{\text{Number of returned surveys}}{\text{Total number of surveys}}\times100\%$.
## Step2: Substitute values
We have the number of returned surveys as 717 and the total number of surveys as 5000. So, $\text{Percentage}=\frac{717}{5000}\times 100\%$.
## Step3: Calculate the percentage
$\frac{717}{5000}\times100\% = 0.1434\times100\%=14.34\%$. Rounding to the nearest whole - number, we get 14%.
In general, a response rate of 14% is considered low. A very low response rate can lead to non - response bias, where the opinions or characteristics of those who did not respond may differ from those who did respond, thus affecting the validity and representativeness of the study results.
# Answer:
Of the 5000 surveys, 14% were returned. This response rate appears to be low.
