Question

Studies have suggested that alcohol abuse and disorders are found to be more prevalent during early adulthood than in any other age group, with about 9% of young adults (age 18 to 29 years) meeting the criteria to be labeled as alcoholic. In addition, surveys have shown that college students tend to drink more than their peers who do not attend college.

You want to test to see if there are differences in excessive alcohol use in young adults that attend college versus those who do not, so you surveyed 405 young adults, age 19 to 22, about their alcohol use by asking the question, "Have you consumed alcohol to the point of intoxication at least once within the past month?" with the following results.

Young Adults Attending College

Young Adults Not Attending College

n₁ = 255

n₂ = 150

y₁ = 96

said "yes"

y₂ = 44

said "yes"

p̂₁ =

255

p̂₂ =

150

(a)

Calculate the test statistic. (Round your answer to two decimal places.)

(b)

H₀: p₁ = p₂

and

H_a: p₁ ≠ p₂,

? = 0.05,

you would do which of the following? (Use a table or SALT.)
