The survey results are not at risk for any bias.
I think the survey is not at risk of either nonresponse bias, nor undercoverage bias. The fact that the survey was handed out by the human resources department means that they participants would have to take it more seriously than they normally would. And as such, even if any other bias would come through, it definitely won't be undercoverage, nor would it be nonresponse bias.

Number of boys enrolled is 105
<em><u>Solution:</u></em>
Given that, At a local preschool there is s as ratio of 3 boys to every 4 girls
There are 245 total preschoolers
Ratio of boys and girls = 3 : 4
Number of boys : number of girls = 3 : 4
Let the number of boys be 3x
Let the number of girls be 4x
Total number of preschoolers = 245
Therefore,
number of boys + number of girls = 245
3x + 4x = 245
7x = 245
x = 35
Number of boys = 3x = 3(35) = 105
Thus number of boys is 105
