(a) Write the estimated regression equation. y= 6.1092 +0.8951x D webassign.net (b) Use a t test to determine whether monthly maintenance expense (dollars per month) is related to usage (hours per week) at the 0.05 level of significance. State the null and alternative hypotheses. Ho: P0 Ha B = 0 Hoi Po = 0 Ha: Bo #0 Ho: B 20 B1 Ha: B < 0 Ho: Po 0 H: Po = 0 Ho P = 0 Ha B = 0 Find the value of the test statistic. (Round your answer to two decimal places.) 6.01 Find the p-value. (Round your answer to three decimal places.) p-value = .0003 State your conclusion. Do not reject Ho. We conclude that the relationship between maintenance expense (dollars per month) and usage (hours per week) is significant. Reject Ho. We conclude that the relationship between maintenance expense (dollars per month) and usage (hours per week) is significant. Reject Ho. We cannot conclude that the relationship between maintenance expense (dollars per month) and usage (hours per week) is significant. Do not reject Ho. We cannot conclude that the relationship between maintenance expense (dollars per month) and usage (hours per week) is significant. (c) Use the estimated regression equation to predict monthly maintenance expense (in dollars per month) for any terminal that is used 25 hours per week.
