degrees of freedom. The obtained p value (0.645) is not greater than the 95 %
confidence intervals and the calculated t value (0.463) does not exceed the table
t value of 1.960. Therefore, the null hypothesis could not be rejected and the two
means (

m M ) are not statistically significantly different at the 5 % level of
significance. There is no significant experience difference in the ease of use for the
K-Mobile Banking PLUS application.
In Table 10.6 , the Levene's test for equality of variances shows that the F ratio
(0.239) is not significant (p

different. Thus, equal variances were presupposed with a t value of

dence interval and the calculated t value ( 0.398) does not exceed the table t value

of 1.960. Therefore, the null hypothesis could not be rejected and the two means

application. That prior experience of using a touch screen system on a mobile phone
