平均值的差异是- 0.557，从数学上来说，AGL得到的响应的均值比单纯能量得到的响应的平均值要低。上述测试所得到的t统计量为- 4.184，而从t表中得到的t统计量的相应临界值为2.617到2.576之间。比较的结果总是与t统计量的绝对值(4.184)作比较。显然，得到的测试统计量超过临界值。因此，零假设被拒绝。这意味着这两种方法不相等。由于这两种方法在数学上不相等，所以可以说，简单的能量比AGL更有意义。
The difference in the mean is -0.557 meaning that mathematically, the mean of the responses obtained for AGL is lower than the mean of the responses obtained for Simply Energy. The t-statistic obtained for the above test is -4.184 whereas the corresponding critical value of the t-statistic obtained from the t-table at 1% level of significance is somewhere between 2.617 and 2.576. The comparison is always made with the absolute value of the t-statistic i.e. 4.184. Clearly, the obtained test statistic exceeds the critical value. Thus, the null hypothesis is rejected. It implies that the two means are not equal. Since the two means are not equal, mathematically, it can be said that Simply Energy has a higher mean than AGL.
Suggestions and Recommendations
Thus, from the above discussion, it can be concluded that the mean of the two response sets are not equal. Clearly, the mean of Simply Energy is higher. It implies that that consumer prefer Simply Energy more than AGL. It is more likely that a person picked at random will prefer to get associated with Simply Energy than with AGL. The reason behind this will simply be the fact that the customers have a stronger trust on the former as compared to the latter. So, assuming that customers with higher trust on Simply Energy will prefer to adapt with the new monthly payment of plan of the firm, it can be safely concluded that the new energy plan taken out by Simply Energy will be widely accepted.
With this in mind, it will be advisable for Simply Energy to cash-in on the opportunity of growing trust and reliability on the firm. Using consumer referral and word of mouth marketing strategies among others, Simply Energy should focus on grabbing the market and ensuring a bigger presence in the target segment. Competing with AGL is not going to be an easy task because they have a very steep learning curve due to their existence in the market since the late nineteenth century. However, Simply Energy has the zeal and the innovation of the youth with growing consumer reliability. If the firm takes proper steps, it can very easily expand in the market to compete more efficiently with a giant like AGL.
