1. A brewery claims that the mean amount of beer in their bottles is at least 12 ounces. Determine whether the hypothesis test for this claim is left-tailed, right-tailed, or two-tailed.

2. The dean of a major university claims that the mean time for students to earn a Master's degree is at most 5.2 years. If a hypothesis test is performed, how should you interpret a decision that fails to reject the null hypothesis?

I greatly appreciate any one's help. These are problems I have struggled with this semester....and now that the end is winding down I would love to figure them out for future references. Thank so much to everyone!
