Look at the scatter-plot diagram with the eruption duration and waiting times for the Old Faithfull geyser. Old Faithful Eruptions What trend does the scatter plot suggest about the relationship between eruption duration and waiting time between eruptions? As eruption duration increases, waiting time decreases As eruption duration increases, waiting time increases There is no clear relationship Waiting times are longest for the shortest and longest eruptions

The following data represent the time between eruptions and the length of eruption for 8 randomly selected geyser eruptions. Complete parts (a) through (c) below. Time, x Length, y 12.12 1.88 11.72 1.77 11.56 1.76 12.21 1.89 12.01 1.79 11.63 1.72 12.16 1.84 11.66 1.71 11.28 1.66 (a) What type of relation appears to exist between time between eruptions and length of eruption? A. Linear, negative association B. Linear, positive association C. A nonlinear pattern D. No association (b) Does the residual plot confirm that the relation between time between eruptions and length of eruption is linear? A. Yes. The plot of the residuals shows a discernible pattern, implying that the explanatory and response variables are linearly related. B. No. The plot of the residuals shows no discernible pattern, implying that the explanatory and response variables are not linearly related. C. Yes. The plot of the residuals shows no discernible pattern, so a linear model is appropriate. D. No. The plot of the residuals shows that the spread of the residuals is increasing or decreasing, violating the requirements of a linear model. (c) The coefficient of determination is found to be 87.9%. Provide an interpretation of this value. The least squares regression line explains __% of the variation in time between eruptions and length of eruption. (Type an integer or a decimal. Do not round.)

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?

For 40 eruptions of the Old Faithful geyser in Yellowstone National Park, duration times (sec) were recorded along with the time intervals (min) to the next eruption. The paired durations and interval times were used to obtain the results shown in the accompanying STATDISK display. Is there sufficient evidence to support the claim that there is a linear correlation between the durations of eruptions and the time intervals to the next eruptions? Explain.
