Answer:
c. Asking people leaving a local election to take part in an exit poll
Step-by-step explanation:
Asking people leaving a local election to take part in an exit poll best represents the highest potential for nonresponse bias in a sampling strategy because of the importance of the local election compared to the exit polls.
It is worthy of note that nonresponse bias occurs when some respondents included in the sample do not respond to the survey. The major difference here is that the error comes from an absence of respondents not the collection of erroneous data. ...
Oftentimes, this form of bias is created by refusals to participate for one reason or another or the inability to reach some respondents.
Answer:
18 men attended the baseball game, and 30 women attended the baseball game.
Step-by-step explanation:
Let the number of men in attendance be x and the number of women in attendance be x+12.
No. of men + <em>No. of women</em> = <u>48 </u>
x +<em> x + 12</em> = <u>48</u>
2x + 12 = 48
2x = 48 - 12
= 36
x = 36 ÷ 2
x = 18
x+12: 18 + 12 = 30
Since we have 2 numbers, we'll be square rooting.
All we have to do to find the mean is multiply & square root the products.
30 × 6 = 180
You can use the same process and check my answer if you'd like; I rounded the square root, so you may get a different answer.
1, 3, 5 are functions because they pass the vertical line test
