According to the given information, the obtained t-value is 2.78 which can be found using the formula t = (mean difference - hypothesized mean difference)/(standard error of the difference). This t-value can be compared with the critical t-value at a given significance level and degrees of freedom to determine if the null hypothesis can be rejected or not.
