According to Inc.com, 79% of job seekers used social media in
their job search in 2018. Many believe this number is inflated by
the proportion of 22- to 30-year-old job seekers who use social
media in their job search. Suppose a survey of 22- to 30-year-old
job seekers showed that 314 of the 370 respondents use
social media in their job search. In addition, 279 of the
370 respondents indicated they have electronically submitted a
resume to an employer.
(a)
Conduct a hypothesis test to determine if the results of the
survey justify concluding the proportion of 22- to 30-year-old job
seekers who use social media in their job search exceeds the
proportion of the population that use social media in their job
search. Use 𝛼 = 0.05.
State the null and alternative hypothesis. (Enter !=
for ≠ as needed.)
H0:
Ha:
Find the value of the test statistic. (Round your answer to two
decimal places.)
Find the p-value. (Round your answer to four
decimal places.)
p-value =
State your conclusion.
Do not reject H0. We cannot conclude
that the proportion of 22- to 30-year-old job seekers who use
social media in their job searches exceeds the proportion of the
population that use social media in their job searches.
Reject H0. We can conclude that the
proportion of 22- to 30-year-old job seekers who use social media
in their job searches exceeds the proportion of the population that
use social media in their job searches.

(b)
Conduct a hypothesis test to determine if the results of the
survey justify concluding that more than 70% of 22- to 30-year-old
job seekers have electronically submitted a resume to an employer.
Using 𝛼 = 0.05, what is your conclusion?
