Two wine tasters rate each wine they taste on a scale of 1 to 5. From data on their ratings of a large number of wines, we obtainthe following probabilities for both tasters' ratings of a randomly chosen wine:Taster 11234510.030.020.0120.000.02Taster 230.0140.000.07 0.20 0.070.00 0.02 0.06 0.200.01 0.010.07 0.06 0.02 0.0150.000.010.020.02 0.06Taster 1's rating for a wine is 3. What is the conditional probability that Taster 2's rating is higher than 3?

cording 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 nemploved 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 b opening. Their answers are shown in the accompanying table. Using a = 0.10, complete parts a through d. Click the icon to view the data on résumés received, a. State the null and alternative hypotheses.
