Answer:In a survey of 525 subjects, each was asked how often he or she read a book. The survey subjects were interest users who responded to a question that was posted on a news website. It is flawed because it is a voluntary response sample 2. In a survey of 663 human resource professionals, each was asked about the importance of the education of a job applicant. The survey subjects were randomly selected by pollsters from a reputable market research firm. It appears to be sound because the data are not biased in any way 3.

Self- interest study 4. Based on a study of weights of men and woman who are vegetarian, a searcher concludes that eating vegetables causes people to lose weight.
Answer: the student's score closest to 91 percentile.
Step-by-step explanation:
Since the scores on the standardized test are approximately normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = test scores.
µ = mean score
σ = standard deviation
From the information given,
µ = 480
σ = 90
If a student has a score of 600, then x = 600
For x = 600,
z = (600 - 480)/90 = 1.33
Looking at the normal distribution table, the probability corresponding to the z score is 0.91
the student's score closest to 91 percentile.
The answer is A because the slope is 25 and y intercept is 100.

4 ) >
5) >
6) >
7) 9
8)19
Step-by-step explanation:
1)
-3.83
rational number because it can be written as -383/100 which is a ratio
2)
√13
irrational number because it can not be written as ratio
3)
