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, 281 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 a = 0.05. State the null and alternative hypothesis. (Enter != for as needed.) HO: H: 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. Reject H . 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. O Reject Ho. 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 O Do not reject Ho. 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. Do not reject H . 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.

(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 a = 0.05, what is your conclusion? State the null and alternative hypothesis. (Enter != for as needed.) Ho: H: 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. O Do not reject H . We can conclude that more than 70% of 22- to 30-year-old job seekers have electronically submitted a resume to an employer. O Reject H. We can conclude that more than 70% of 22- to 30-year-old job seekers have electronically submitted a resume to an employer. O Reject Ho. We cannot conclude that more than 70% of 22- to 30-year-old job seekers have electronically submitted a resume to an employer. O Do not reject H . We cannot conclude that more than 70% of 22- to 30-year-old job seekers have electronically submitted a resume to an employer.
