The p-value is...
This test statistic leads to a decision to...
As such, the final conclusion is that...
The statistical software output for this problem is :
Test statistics = 0.6209
P-value = 0.2683
The p-value is greater than α .
fail to reject the null hypothesis .
There is not sufficient sample evidence to support the claim that the population mean is greater than 54.3.
