The data is dividing into halves thus reliability in the two halves. The output is alpha 0.9051 refers to extent to which its consistent measure of concept.b)Cronbach’s test to determine if there existed biasness in splitting. c)The alpha 0.9051>0.7 thus high reliabilityQuestion 6a)Test- Retest is to construct a reliable measurement scale, to improve the scales and finallyevaluate the scale in use.b)Calculate the coefficient alpha which will identify the reliability of the scales.c)The reliability coefficient 0.6559 <0.7 thus the scale are less reliable. Question 7a)Pearson correlation measures linear correlation between two variables. When output is 1, positive linear correlation. When output is 0, no linear correlations while -1 indicates a negative linear correlation. b)Correlation between satisfaction and unreliability is -.5 thus weak negative correlation, intent to buy .764 thus positive correlation and friendly 0.18 hence weak positive correlation.Correlation between unreliability and intent to buy and friendly -.35 and 0.5 are weak negative and positive correlations respectively.Correlation between intent to buy and friendly are 0.007 which is weak positively correlated.Correlation between satisfaction and friendly is weakly positively correlated. c)The output is logical since all these values are between 1 and -1. They are within the range.d) The unreliability of the supply company gave dissatisfaction to the buying company. Question 8 a)Pearson correlation measures linear correlation between two variables.
