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 0.05 significance level. identify the null and alternativehypotheses, test statistic, p-value, and state the final conclusion that addresses the original claim. what are the null and alternative hypotheses? a. upper h 0h0: muμequals=00 minutes upper h 1h1: muμless than< 00 minutes b. upper h 0h0: muμequals=00 minutes upper h 1h1: muμnot equals≠00 minutes c. upper h 0h0: muμequals=00 minutes upper h 1h1: muμgreater than> 00 minutes d. upper h 0h0: muμless than< 00 minutes upper h 1h1: muμequals=00 minutes identify the test statistic. nothing

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.
