Answer to Question 1

a. H0:  = 10 seconds vs. H1:  > 10 seconds
b. The null hypothesis represents the 'status quo.' In other words, it's what you would believe unless there is sufficient evidence against it. It represents the original claim. The alternative hypothesis is what you suspect is true, and what you want to show is true by providing sufficient evidence against H0.
