According to Inc, 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 306 of the 370 respondents use social media in their job search. In addition, 283 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. b) 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.) c) Make the decision and state your conclusion.
