Determine whether the following series converges absolutely, converges conditionally, or diverges. Find lim ak. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. Now, let ak denote the sum. What can be concluded from this result using the Divergence Test? Are the terms of the sequence ak decreasing after some point? Let ak denote the sum. What can be concluded from these results using the Alternating Series Test? Does the series converge? Does the series converge absolutely, converge conditionally, or diverge?

1. The built-in data set faithful gives data on eruptions of the Old Faithful geyser in Yellowstone National Park. Each observation has a length of time the eruption lasted ( eruptions ) and the length of time until the next eruption ( waiting ), both in minutes. a. Find the equation of the regression line to explain waiting as a function of eruptions. b. Plot the data and the regression line. c. How long do you expect to wait after a 4.3 minute eruption?

Researchers in Yellowstone National Park are studying the Old Faithful geyser. They want to use the length of each eruption to predict the amount of time that will elapse before the next eruption. In particular, they believe that when the geyser erupts for a longer period of time, the amount of time before the next eruption will also be longer. Below are the lengths of 16 randomly chosen eruptions along with the amount of time until the next eruption. The two data sets are in the same order and are both measured in minutes. Eruption length: 3.9, 4.3, 2.2, 3.7, 4, 1.9, 5.3, 4.3, 4.5, 1.9, 4.5, 2.2, 2.1, 4, 1.8, 3.3 Time to next eruption: 69, 87, 60, 71, 108, 50, 77, 89, 84, 60, 80, 60, 49, 92, 43, 74 Conduct a hypothesis test to determine whether there is evidence that when the geyser erupts for a longer period of time, the amount of time before the next eruption will also be longer. Step 1: State hypotheses. Step 2: Verify whether the conditions are met for the hypothesis test (even if one of the conditions is not met, continue with the rest of the hypothesis test). Step 3: Report the P-value of the test. Step 4: State the conclusion using a significance level of α = 0.05, both in statistical terms and in the context of the problem.
