Dependent Variable: Y Description: • Reliability variable (X1) has a positive and significant effect on customer satisfaction, this can be seen from the significant value (0.000) below than (smaller than) 0.05 and the value of t count(4,576) > ttabel means that if you increase the Reliability variable (X1) by one unit (unit), then customer satisfaction (Y) will increase by 0.287 units • Assurance variable (X2) has a positive and significant effect (0.204) below (smaller than) 0.05 and the value of t count(1,279) > ttabel means that if the Reliability variable (X1) is increased by one unit (unit), customer satisfaction (Y) will increase by 0.190 units (unit). • Tangible variable (X3) has a positive and significant effect (0.347) below (smaller than) 0.05 and the value of t count(0,945) > ttabel means that if the Reliability variable (X1) is increased by one unit (unit), customer satisfaction (Y) will increase by 0.156 units (unit). • Emphaty variable (X4) has a positive and significant effect (0.712) below (smaller than) 0.05 and the calculated t value(0,371) > ttabel means that if the Reliability variable (X1) is increased by one unit (unit), customer satisfaction (Y) will increase by 0.037 units (unit). • Variable Responsiveness (X5) has a positive and significant effect (0.581) below (smaller than) 0.05 and the value of t count(0,555) > ttabel means that if the Reliability (X1) variable is increased by one unit (unit) then customer satisfaction (Y) will increase by 0.141 units (unit) • Based on the output results, the formula for the regression equation is: Y = β0 + x1 + β3 x3 +β x44 + β5 x5 + ei Y = 2.916 + 0.287 X1 + 0.190 X2 + 0.156 X3 + -0.037 X4 + 0.141 X5 + ei
