Question
According to a job website, each job opening on average attracted 251 résumés in 2016. The job market improved in 2017 compared to 2016, which means that more people will likely be switching jobs but also fewer
unemployed workers remain in the job market. To find out which trend is stronger, a random sample of 20 employers in a region was taken. Each employer reported how many résumés they received in 2017 for each
job opening. Their answers are shown in the accompanying table. Using a = 0.10, complete parts a through d.

a. State the null and alternative hypotheses.
Determine the null hypothesis, Ho, and the alternative hypothesis, H,.
