Under regression, we shall use the p-value to show if eruption time is a significant predictor of the waiting time.

1.4 Descriptive Statistics
Table 1: a summary of descriptive statistics eruptions | | | waiting | | | | | | | | | Mean | | 3.487783088 | Mean | | 70.89706 | Standard Error | | 0.069205797 | Standard Error | | 0.824316 | Median | | 4 | Median | | 76 | Mode | | 1.867 | Mode | | 78 | Standard Deviation | | 1.141371251 | Standard Deviation | | 13.59497 | Sample Variance | | 1.302728333 | Sample Variance | | 184.8233 | Kurtosis | | -1.506167098 | Kurtosis | | -1.14153 | Skewness | | -0.418150471 | Skewness | | -0.41863 | Range | | 3.5 | Range | | 53 | Minimum | | 1.6 | Minimum | | 43 | Maximum | | 5.1 | Maximum | | 96 | Sum | | 948.677 | Sum | | 19284 | Count | | 272 | Count | | 272 |

Summary;
From the table comparing the standard deviation, the eruption time has a smaller standard deviation than that of waiting time. the eruption time is positively skewed while the waiting time is negatively skewed. This shows that for the eruption time most of the values are to the left of the mean with extreme values to the right. On the other hand, for the waiting time most of the values are to the right of the mean with extreme values to the left.
From the descriptive statistics, we can
