It is believed that about 35% of high school students vape (This includes nicotine flavored liquids, marijuana, and hash oil). Researchers conducted a study of 425 students to determine if the proportion of high school students who vape is different from 35%. From their study they found that 155 high school students admit to vaping. State the value of the relevant statistic (round your answer to 3 decimal places).

1. What is the relevant statistic?
2. What is the 95% confidence interval?
3. What are the null and alternative hypothesis?
4. Is it plausible that 38% of all high school students vape?

Which of the following are possible examples of sampling distributions? (Select all that apply.)

a.) all mean trout lengths in a sampled lake

b.) heights of college students at a sampled university

c.) average male height based on samples of size 30

d.) mean trout lengths based on samples of size 5

e.) average SAT score of a sample of high school students

Determine whether the underlined value is a parameter or a statistic.

The average score for a class of 28 students taking a calculus midterm exam was 72%. Is the value a parameter or a statistic?

A. The value is a parameter because the class of 28 students is a population.

B. The value is a statistic because the class of 28 students is a sample.

C. The value is a statistic because the class of 28 students is a population.

D. The value is a parameter because the class of 28 students is a sample.
