Park officials make predictions of times to the next eruption of a particular geyser, and collect data for the errors (minutes) in those predictions. The display from technology available below results from using the prediction errors to test the claim that the mean prediction error is equal to zero. Comment on the accuracy of the predictions. Use a significance level. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. 0.05 Click the icon to view the display from technology. 1 Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses?.........................

Choose the correct answer below. A. The population mean, , is equal to 1. B. The sample is a simple random sample. C. The value of the population standard deviation is not known. D. Either the population is normally distributed or n 30 or both. > 1: Display from Technology Park officials make predictions of times to the next eruption of a particular geyser, and collect data for the errors (minutes) in those predictions. The display from technology available below results from using the prediction errors to test the claim that the mean prediction error is equal to zero. Comment on the accuracy of the predictions. Use a significance level. State the final conclusion that addresses the original claim. . There is evidence to conclude that the original claim that the mean prediction error is equal to zero correct. There is in the mean prediction. 2: Display from Technology A data set includes data from random tornadoes. The display from technology available below results from using the tornado lengths (miles) to test the claim that the mean tornado length is greater than miles. Use a signi...
