The owner of a moving company wants to predict labor hours, based on the number of cubic feet moved. A total of 34 observations were made. An analysis of variance of these data showed that b1=0.0426 and Upper Sb1=0.0065.
a. At the 0.05 level of significance, is there evidence of a linear relationship between the number of cubic feet moved and labor hours?
b. Construct a 95% confidence interval estimate of the population slope β1.
a. Determine the hypotheses for the test.
t stat = ?
Critical values = ?
Reach a decision
Reject or do not reject H0. There is sufficient or insufficient evidence to conclude that there is a linear relationship between the number of cubic feet moved and labor hours.
The 95% confidence interval = ?

The owner of a moving company typically has his most experienced manager predict the total number of labor hours that will be required to complete an upcoming move. In a effort to provide a more accurate method, the owner has decided to use the number of cubic feet moved as the independent variable and has collected data for 20 moves in which the travel time was an insignificant portion of the hours worked.

The owner of a moving company usually has her most experienced
manager predict the total number of labor hours required to
complete a move. While useful, the owner is interested in a more
accurate method of predicting the number of labor hours required.
As a preliminary effort, data was collected on the number of work
hours required to complete a move, number of cubic feet moved, the
number of large pieces, and if an elevator was present.
