Question
data show the time intervals after an eruption (to the next eruption) of a certain geyser Find the regression equation, letting the frst varable be the the ieterval after an eruption given that the cuent eruption has a height of 95 feet Use a significance level of 0.05 independent () vanable Find the best predcled time of 115 133 137 140 99 112 108 126 interval afer (mi l Ckck the icon to view the critical values of the Pearson cometation coeftmicient What is the regression equation? .LxRound to wo decimal places as needed ) What s the best predicted time for the interval after an eruption that is 95 feet high? The best predicted interva sme tor an eruption that s 95 feet high sm Round to one decimal peace as needed the answer boxesExplanation / Answer
a) Regression Equation would be
y = 17.22+0.52x
b) For x = 95
y = 17.22+0.52*95
y = 66.7
