Answer: toeboard
Explanation: The Occupational Safety and Health Administration defines the Walking-Working surfaces regulation for the secure construction of stairs in industrial environments. For platforms or walls that are 4 feet or higher above the ground and do not have surrounding walls, it is mandatory to build a standard railing around them. In cases where there is a moving machinery, people can pass or there is an equipment which would be harmful when falling objects come in contact with it, the railings must have a toeboard.
A toeboard is an equipment fixed vertically to prevent items from falling for the platform.
Answer:
There will be 16 people who are both writer and editor
Explanation:
We have given there are total of 100 people
So total = 100
There are 45 writers so,Writers = 45;
It is given that there are more than 38 editors so ,Editors > 38
Both = x;
Neither = 2x
We know that
Total = Writers + Editors - Both + Neither
100 = 45 + Editors - x + 2x
x = 55 - Editors
We want to maximize x, thus we should minimize Editors minimum possible value of Editors is 39, thus:
x = Both = 55 - 39 = 16.
Answer:
3. This will lead to a biased sample because the type of students who take Psychology and Law may be different from the type of students who take Introduction to Neuroscience

Professor Kramer wants to measure the level of happiness of his students, and he wants to do so for both his classes. However, he will biased the survey simply because he is considering surveying only the students from one of his classes, who may be very different from the students from the other class.
If Professor Kramer wants to make a unbiased survey, he should either find a way to also apply the survey to the students from the other class, or change the goal of the research to measuring the happiness level of the Psychology and Law class students only.
