Old Faithful is a geyser located in Yellowstone National Park in Wyoming, USA. Millions of travelers come from afar to witness Old Faithful's eruptions each year. The data provided show the waiting time until the next cruption for 272 Old Faithful eruptions in 1990 Click to download the data in your preferred format. Crunchit CSV Excel IMP Mac Text Minitab14-18 Minitab18+ PC Text R SPSS TI Calc Suppose that prior to 1990, travelers to Yellowstone are told that Old Faithful is expected to erupt, on average, every 69 minutes, and park scientists believe that this average is no longer true. Suppose that, based on historical data available over several decades, the scientists are comfortable assuming that all eruption waiting times have a known standard deviation of 17.248 minutes. Use software to calculate the sample mean() for these data. Then, conduct a one-sample, two-sided 2-test to test the park scientists' claim at the a = 0.05 level. Calculate the standard error (SE), z-statistic, and the positive z-critical value for this test. Please round all answers to the nearest three decimal places. X: SE: z-statistic:
SE: 2-statistic: 2-critical value: Based on your z-statistic and z-critical value, what can you conclude about the park scientists' claim that the average time between cruptions of Old Fuqhful has changed? at the The correct decision is to the null hypothesis because there is a = 0.05 level that the mean waiting times until the next eruption are different than previously claimed
