Twenty-five assembly-line workers participated in a study to investigate the relationship between experience and the amount of time required to complete an assembly task. Assembly time (in minutes) and number of months the worker had been employed on the assembly line were measured for each worker. The resulting data on y= time to complete assembly and x= number of months on the assembly line were used to produce the scatterplot and computer output below.

S= 9.79097 R-Sq = 62.0% R-Sq(adj) = 60.4%
Predict the time required to complete the assembly for an employee with 10 months of experience.
A) 81.6min
B) 90.6min
C) 110.4min
D) 120.7min
E) 150.3min
